MAINTENANCE
4.0 TROUBLESHOOTING
When supplied with power, the top panel PWR LED should light. If the PWR
LED blinks, the battery is low and must be replaced or recharged. If the PWR
LED does not illuminate at all, verify LED operation by keying the transmitter
and verifying the TX indicator lights. If the TX LED does not illuminate,
attach different battery pack and retry. If the LED still does not illuminate
return the unit for repair.
If the unit will not descramble the signal from another unit :
a. Insure that both units are set to the same channel operation.
b. Insure that both units are set to the same code setting.
NOTE:
Both units must be operating with the same code to achieve communications.
Field personnel will not be able to verify the actual codes associated with
common or private operation. If necessary, the issuing office should re-load
the codes or return the units to ATS.
c. Verify that the antenna is properly connected to the antenna jack.
d. Return the unit to the factory for repair.
4.1 MAINTENANCE
The Model 1225 is designed for simple installation and use. There are no
user maintenance requirements.
4.2 KEY LOADER
If the LOAD FAIL indicator lights, the key load sequence did not succeed.
If the this occurs
a. Check the setting of the KEY NUMBER switches to ensure that it is
not set above 300,
b. Verify that the interface plug on the Model 1260 cable is fully
seated into the KEY LOADER connector on the Model 1225,
c. Continuing LOAD FAIL indications mean that either the Model 1260 or
the Model 1225 is defective and should be returned for repair. If a Model 1260
is suspected of failure, it should be tried with another Model 1225. If
failures still occur, the Model 1260 is defective.
4.2 REPAIRS
Repairs to the Model 1225 should be performed by an authorized factory
representative.
