2. Before connecting and disconnecting the power connec-
tor be sure to turn OFF the POWER switch on the front
penel of the transceiver and the power supply.
3. Observe proper polarities when connecting the OC power
cable to the supply.
Remember red is positive and biack is negative.
3-2-3. Antenna
The type of antenna that is used will greatly affect the per-
formence of the transceiver. Use a properly adjusted anten-
na, of good quality, to enable your transceiver to perform
at its best. The antenna input impedance is 50 ohms. Use
60 ohm coaxial cable such as RG-8U or 8D-2V for this con-
nection. If the antenna is far from the transceiver the use
of low loss cable is recommended. Match the impedance
of the coaxial cable and that of the antenna so that the SWR
will be less than 1.5 to 1. The protection circuit in the tran-
sceiver will activate if the SWR is particularly poor (greater
than 3 to 1). High SWR values will cause the transmitter
output to fail off and may lead to TVI or BCI reports.
CAUTION: ee ee teeta bone eee
We recommend that you instail a high quality lightening ar-
restor in your antenna lines for protection against fire, elec-
tric shock, personal injury, or damage to the radio itself.

(1) POWER ewitch
Press to turn the traneceiver ON or OFF,
(2) Tuning control
This contro! is used to select the desired transmit-
ter/receiver frequency, Memory Channel, Frequency
Step, Tone Frequency, Scan Direction, eto.
@ VOL control
This control le used to adjust the volume from the Inter-
nal and extemal epeaker (if used), Clockwise rotation will
increase the volume and counterclookwise rotation will
decrease the volume.
