Initial Step to Take

Use a Tablet / Phone that you know is working correctly and try this on the unit you suspect has a bad amplifier to test it. This will let you know if there may be an issue with the tablet/ phone settings or software. Which you will need to check. If it still does not work the proceed below.

Step 1

Please confirm the on/off rocker switch is in the “ON” Postion

·     Check to see if the Blue LED light is on

·     If Blue LED is on, we know there is power to the amplifier.

Step 2

Check Amplifier Cable

·     Look behind amplifier and make sure power cable is firmly seated into the amplifier unit.

·     Check for bad LED Light if no Blue LED is on in step 1. If it is on in step one go directly to Step 3.

·     Make sure audio cable is connected to tablet / phone and amplifier.

·     Go to settings and find ringtones in your tablet / phone. Select a ringtone and play it. If you heard the ringtone you have a burned-out LED bulb, continue to Step 3 if you did not hear the ringtone.

·     If LED is burned out, you can send an email to GPSLockbox Service Dept. for a replacement unit.

Step 3

Check Fuse

·     The fuse should be near the electrical panel where the power cable is connected to a 12volt source.

·     Find the fuse holder and check the fuse and replace if necessary. The fuse should be 5amp.

·     If the fuse is good you need to confirm the amplifier is connected to constant power. Use a voltage meter to check that you have 12volt constant power. If not change connection to a constant 12volt.

·     If you do not have a voltage meter, you can try by turning on the ignition and see if you now have power to the amplifier.  Amplifier still not on then you may have a bad unit Step 4 next.

 

(In some cases, installers may have the 12Volt constant connected to an ignition that is why turning the ignition on should be tested.)

Step 4

Bad Amplifier No Power

·     Email GPSLockbox Service Dept. at service@gpslockbox.com for a replacement amplifier. We will send one out as soon as possible.
