d. Clean the front panel displays and keypad with a soft clean cloth. If dirt is difficult to remove,

dampen the cloth with water; mild soap may be used for more effective cleaning.

CAUTION

1. Do not press on the display window faces when cleaning.

2. Do not use solvents for cleaning display window, keypad and

push-buttons.

3. Do not use compressed air for cleaning the panel. This may damage the

push-buttons.

5-3. CORRECTIVE MAINTENANCE

The scope of corrective maintenance at the operator level is to return the radio set to normal operation

as soon as possible, by replacing cables, accessories, or equipment units suspected of being defective.

Replaced items shall be sent for repair at a designated maintenance facility.

In case a fault is detected, or the radio set fails to operate, perform the following steps and repeat the

communication check until the problem is corrected:

1. Visually inspect the radio set, and make sure that the radio set is assembled properly and ready

for operation.

2. Replace the battery with a freshly-charged battery, and then check again.

3. Turn the radio set off, and then turn it back on, and monitor the display: every time the radio is

turned on, a self-test procedure is performed. If an internal malfunction is found, an error

message will be displayed.

4. Activate the BIT function, using MENU>BIT. You have three options:

• FULL – runs a full test of the Micom Pathfinder.

• CHAN – tests Micom Pathfinder operation on the current channel.

• L.RF – tests the Micom Pathfinder receive path only.

NOTES

1. To obtain reliable results, it is necessary to perform the test under

controlled conditions. This is achieved by disconnecting the

external antenna, and connecting a 50Ω dummy load or 30 dB

attenuator with a suitable power rating (30W or more) to the

DIPOLE connector (make sure to select NONE on PROG > RAD >

OPTS > ACC when using a dummy load).

2. It is not necessary to connect a load when performing only the

L.RF test.

3. If the Micom Pathfinder includes an internal modem or vocoder,

make sure to perform the test in the clear (CLR) mode.

Select the test best suited to the detected problem, and wait a few seconds for the test to

complete.

Refer to Table 5-2 and perform the corrective actions listed for the corresponding message, until the

problem is corrected. If the message does not appear in Table 5-2, or the problem persists, the radio set

must be serviced.
