C. Troubleshooting

Power

Problem: The meter’s display is blank and the LEDs are not flashing.

Solution: Be sure to turn the meter on. This can be done by inserting any card into the

meter. Insert it completely up the card slot and wait for a beep.

If this fails, be sure the battery is plugged in. Also, verify that the card reader

connector is attached to the solar panel and that the solar panel is fully

connected to the main board.

Problem: The meter’s display is blank but the LEDs are on continuously.

Solution: Replace the battery.

Problem: In the Voltage Menu item of the Diagnostic Menu, the Solar Panel voltage is

reported as being extremely low (i.e. under 500 mV).

Solution: Verify that the Solar Panel is properly connected to the Main board and there

is nothing obstructing the Solar Panel.

Problem: The display is blank, but the lights are flashing.

Solution: Press the diagnostics button. If text appears on the screen, press Cancel. If

the screen is still blank, inspect the LCD ribbon cable for damage. Verify that

the Display Board is fully connected to the Main board.

Coin Issues

Problem: The meter reads Cards Only/No Coins. In Diagnostic Mode, the meter

shows “Coin Path Blocked”.

Solution: Check the validator for any obstructions. If the problem persists, check that

the validator is properly plugged in and that the connector cable is not loose.

Also check that the validator connector board is intact.

Problem: The meter reads Cards Only/No Coins. In Diagnostic Mode, the meter shows

“OSC Fault”.

Solution: Check the validator for any obstructions. Try swapping the validator with

another one as one of the coils of the existing validator may be damaged.

Communication Issues

Problem: During communications, the meter displays “GSM NOT FOUND”.

Solution: Make sure that the Solar Panel Board is properly attached to the Main Board.

Problem: During communications, the meter displays “NO SIM”.

Solution: Verify that the SIM card is fully inserted into the SIM. Remove and replace

the SIM card and force the meter to contact the management system.
