When an arcade cabinet is turned off at night, the main power supply unit (PSU) stops delivering +5V/+12V DC power to the motherboard.
Without an active secondary power source, volatile memory loses all stored data instantly. The CMOS battery acts as a continuous backup power source, supplying microscopic amounts of current to keep the CMOS RAM active so that saved settings remain intact across power cycles.

2. CMOS Battery Applications Across Different Arcade Platforms
CMOS batteries serve two distinct roles depending on whether the arcade machine is driven by a PC motherboard architecture or a specialized microcontroller board:
A. PC-Based Arcade Video Games (3V CR2032 Lithium Cell)
Modern high-end video games run on embedded PC platforms (Intel/AMD motherboards running Windows Embedded, Linux, or custom arcade OS environments).
Example Games: Wangan Midnight Maximum Tune (1–6), Pump It Up, Initial D, Tekken 7, Photo Freestyle, Raw Thrills Racing Games.
Standard Battery Type: CR2032 3V Coin Cell.
Core Function: Preserves hardware BIOS settings (SATA boot drive priority, CPU clocking, onboard I/O configurations) and system real-time clock (RTC).
B. Microcontroller & Redemption Arcade Games (5.5V Supercapacitor / Battery Modules)
Dedicated redemption and skill games often use custom microcontroller boards (MCU) rather than full PC motherboards.
Example Games: Street Basketball, Tower Crane, Claw Machines, Ticket Redemption Games.
Standard Battery/Capacitor Type: 5.5V Memory Backup Battery / Supercapacitor Module (or Ni-MH button stack).
Core Function: Preserves critical arcade operator settings, including:
Credit ratio settings (e.g., 1 card tap = 2 plays).
Ticket payout rates & mercy ticket options.
Game time limits and difficulty calibrations.
Audit meters (total plays, total coins inserted, total tickets dispensed).

3. Symptoms of a Weak or Dead CMOS Battery
A standard CMOS battery has an operational lifespan of approximately 3 to 5 years. When the battery voltage drops below its critical threshold, arcade machines exhibit distinct error behaviors upon bootup:
+-----------------------------------------------------------------------------------+
| CMOS BATTERY FAILURE SYMPTOMS & IMPACT |
+----------------------+----------------------------------+-------------------------+
| Arcade System Type | On-Screen / Hardware Symptom | Operational Impact |
+----------------------+----------------------------------+-------------------------+
| PC-Based Arcade | "CMOS Checksum Error - Defaults | Machine halts on boot; |
| (Maxtune, PIU) | Loaded" or "Press F1 to Continue"| requires keyboard input |
+----------------------+----------------------------------+-------------------------+
| PC-Based Arcade | System Date/Time resets to 1999 | Online ranking, dongle |
| | or 2000 | security check fails |
+----------------------+----------------------------------+-------------------------+
| MCU / Redemption Game| Settings reset to factory default| Credit/ticket payout |
| (Basketball, Crane) | after every reboot | rates lose calibration |
+----------------------+----------------------------------+-------------------------+
Key Indicators:
BIOS Boot Halts: On startup, a PC-based game displays error prompts on the CRT/LCD screen, such as:
CMOS Checksum Error - Defaults LoadedCMOS Battery State LowPress F1 to Run SETUP / Press F2 to Load Default Values
Loss of Game Operator Settings: Every time the machine is restarted or powered on in the morning, ticket payout settings, game difficulty, and credit configurations reset to factory defaults.
Loss of Audit Data: Total earnings, play counts, and ticket payout histories are wiped out, making daily revenue tracking inaccurate.
Boot Sequence Errors: The motherboard forgets which drive holds the game software (e.g., SSD, HDD, or CompactFlash card) and attempts to boot from a non-existent drive, showing
No Boot Device Found.

Replace Cell De-solder / Replace Module
(Observe +/- Polarity) (Check PCB traces for corrosion)
Step 1: Voltage Testing with a Multimeter
Power off the arcade cabinet and unplug the main power cable.
Locate the coin cell holder (or 5.5V backup module) on the main CPU PCB.
Set your multimeter to DC Volts ($V_{DC}$).
Place the red probe on the positive terminal (
+) and the black probe on the negative terminal (-):3V CR2032 Battery: Replace if reading is below $2.8\text{V DC}$ (a healthy new cell reads $\approx 3.2\text{V}$ to $3.3\text{V}$).
5.5V Backup Module: Replace if reading is below $4.5\text{V DC}$ when main power is off.
Step 2: Safe Replacement Procedure
Standard Coin Cells (CR2032): Gently press the metal retaining clip outwards and slide the old battery out. Insert the new CR2032 with the plus sign (
+) facing upward.5.5V Soldered Modules: For arcade boards using soldered 5.5V button-stack batteries or supercapacitors, inspect the PCB surrounding the battery pins for green acid corrosion. De-solder the old module using a soldering iron and desoldering pump, clean the pads with isopropyl alcohol, and solder the new unit observing correct polarity.
Step 3: Re-configuring BIOS & Operator Settings
After replacing the battery:
Power on the machine and access the motherboard BIOS Setup (press
DELorF2using a USB keyboard).Set the correct Date and Time, restore the correct Boot Drive Order, and save changes (
F10).Enter the game’s Operator / Test Menu (using the internal test switch) to re-enter your preferred credit, pricing, and ticket payout ratios.

Beyond standard photo-electric infrared beams, arcade game mechanics rely heavily on Proximity Sensors and Rotary Encoders to detect mechanical positions, coin drops, motor rotations, and physical player movements.
Understanding these components ensures fast diagnostic turns when servicing complex arcade attractions such as ticket redemptions, coin pushers, and carnival-style physical games.

What is a Proximity Sensor (Proximity Switch)?
A Proximity Sensor (or Proximity Switch) is a non-contact detection device that senses the presence or absence of an object when it enters a specific detection zone.
Key Characteristics:
Short Sensing Range: Operates at very close range—typically from 1 mm up to a few centimeters, depending on the sensor model.
Operating Voltage: Standard industrial/arcade variants operate on 10–30 VDC, though high-voltage models operating on 100–200 VAC also exist.
Non-Contact Operation: Prevents mechanical wear and tear, making it ideal for high-vibration arcade environments.

Types of Proximity Sensors Used in Arcades
Proximity sensors are categorized based on the physical properties of the materials they detect:

| PROXIMITY SENSORS |
+-----------------+-----------------+
|
+-------------------------+-------------------------+

• Ignores: Non-metal obstacles Wood, Liquids, Glass, Rubber)
• Arcade Apps: Firefighter, Dino Time • Arcade Apps: Street Basketball, Jungle
Bowling, Disco Winner
1. Inductive Proximity Sensors (Metal Detection Only)
Inductive proximity sensors generate an electromagnetic field at their sensing face. They exclusively detect ferrous metal/iron targets.
Key Feature: If a non-metal object (like plastic, wood, or cardboard) blocks the sensor, the sensor ignores it and continues detecting metallic targets behind or through the barrier—as long as the target stays within the maximum sensing range.
Common Arcade Applications:
Firefighter: Detecting metal lever position or nozzle movement.
Dino Time: Tracking metallic gear alignment, target flaps, or mechanical coin-drop gates.
2. Capacitive Proximity Sensors (Universal Target Detection)
Capacitive proximity sensors measure changes in an electrostatic field. They detect all object types, including metals, plastics, liquids, glass, and wood.
Key Feature: High sensitivity to any dense material passing through its close-range envelope.
Common Arcade Applications:
Street Basketball: Rim-mounted ball passage detection.
Jungle Bowling & Disco Winner: Ball track positioning, plastic target flips, or coin distribution detection.
How to Test and Diagnose Proximity Sensors
You can verify whether a proximity switch is working properly using two practical methods: LED Indicator Visual Inspection or Multimeter Voltage Measurement.
Method 1: LED Indicator Visual Test
Most proximity sensors feature an integrated LED status light on the rear housing:
Active-High / Normally Open (NO) Configuration:
No Target (OPEN): LED is OFF.
Target Present (CLOSED): LED turns ON.
Active-Low / Normally Closed (NC) Configuration:
Target Present (CLOSED): LED turns OFF.
No Target (OPEN): LED turns ON.
Diagnostic Rule: Bring a metal target (for Inductive) or any solid object (for Capacitive) near the sensor face. If the LED toggles cleanly between states, the internal sensing circuit is functioning correctly.
Method 2: Multimeter DC Voltage Test (Signal Pin to Ground)
For deeper troubleshooting when the LED lights up but the main game board still fails to register input:
[ Power Source: 12V / 24V DC ] --------> (VCC Pin - Brown Wire)
[ Ground / Com ] ----------------------> (GND Pin - Blue Wire)
[ Multimeter (+) Probe ] --------------> (Out / Drive Pin - Black or White Wire)
[ Multimeter (-) Probe ] --------------> (GND Pin - Blue Wire)
Supply standard working power (10–30 VDC) to the sensor power wires.
Set your digital multimeter to DC Volts ($V_{DC}$).
Place the red probe on the Signal Output Pin (Drive/Out) and the black probe on Ground (GND).
Observe the voltage response:
State 1 (OPEN): Reads approximately 5V DC (or VCC voltage depending on pull-up logic).
State 2 (CLOSED): Voltage drops to 0V DC.
If the output voltage switches between 5V and 0V cleanly upon bringing a target near, the sensor signal driver is healthy.
Other Essential Arcade Sensors: The Rotary Encoder
While proximity sensors handle basic proximity and position switching, Rotary Encoders (Rotary Sensors) measure continuous mechanical rotation, velocity, and angular direction.

Pulsed signals (A/B) Calculates exact wheel
sent to game board angle and spin speed
How Rotary Encoders Work in Arcades:
Rotary Shaft: Connected directly to steering wheels, ticket wheels, or motor spindles.
Pulse Signal Output: As the shaft spins, the encoder outputs digital pulse trains (Phase A & Phase B signals).
Game Logic: The game board counts these pulses to calculate exact steering angles, wheel spin speeds, or physical ticket distribution counts.
Primary Arcade Applications:
Racing Games: Steering wheel orientation and force-feedback centering (e.g., Mario Kart Arcade GP, Initial D).
Wheel of Fortune / Spinner Games: Measuring spin strength, speed decay, and winning segment position (e.g., Big Bass Wheel, Spin-N-Win).
Ticket Dispensers: Precision counting of physical ticket notches as they pass through the dispenser rollers.
Summary: Quick Sensor Reference Guide
