2.4 BATTERY
The Model 1225 Hand Held transceiver operates from a 1200 mAh or an 1800
mAh Nickel Cadmium, rechargeable battery. The battery slides onto the Model
1225 battery clip assembly located on the bottom of the unit. To remove the
battery, push the retaining clip upwards towards the top of the unit and slide
the battery in the direction opposite the clip. When installing a battery,
insure the grooves on the top of the battery are properly aligned with the
baseplate. The battery should slide on easily.
A blinking PWR LED on the Model 1225 indicates low battery conditions.
The battery should be replaced immediately with a fully charged battery. The
Model 1225 Hand-Held transceiver will operate for approximately 180 minutes in
receive mode or 15 minutes in transmit mode after a battery low condition is
indicated. Only critical transmissions should be made after the battery low
condition is indicated.
2.5 ANTENNA
The Model 1225 is provided with a flexible antenna. The antenna is
screwed into the top panel mounted connector and fits within the cup. No other
antenna should be used with the Model 1225.
2.6 PRIVACY CODES
Privacy keys are stored in non-volatile memory. The keys are loaded into
memory using the Model 1260 Key Loader. If a keyed unit is lost or stolen, the
keys in the remaining units can be changed quickly to maintain the overall
security. Code selection is made using the top panel switch. Two codes
selections are available, common (C) and private (P). The C code is factory set
on all units and provides a common scrambler code for use during inter- agency
operations. The P code is intended to be agency or group specific. The P code
can be changed by the user. In operation, the Model 1225 uses different codes
for Channel A and Channel B operation.
To load a P code into the Model 1225, use the Model 1230-03 Adapter Cable
to connect the Model 1260 Key Loader to the key loader connector located on the
bottom of the Model 1225. The POWER indicator on the Model 1260 should light
(providing the Model 1225 is powered on). Select a code by rotating the KEY
NUMBER thumb wheel switches on the Model 1260. (Selecting a code number above
300 will result in an error indication on the Model 1260.) Depress the LOAD KEY
button on the Model 1260 to download the selected key. The KEY LOADED indicator
on the Model 1260 should light, indicating that the new keys were successfully
loaded into the Model 1225. If the LOAD FAIL indicator lights, the key load
sequence did not succeed.
