DANGER

NEVER

connect the transceiver to an AC outlet or to a DC

power supply that uses more than 16 V. This will ruin the
transceiver.

DO NOT

expose the transceiver to rain, snow or any liquids.

DO NOT

reverse the polarities of the power supply when

connecting the transceiver.

DO NOT

apply an RF signal of more than 20 dBm (100 mW)

to the antenna connector. This could damage the transceiv-
er’s front end.

ORDERING PARTS

Be sure to include the following four points when ordering
replacement parts:

1. 10-digit order numbers
2. Component part number and name
3. Equipment model name and unit name
4. Quantity required

REPAIR NOTES

1. Make sure a problem is internal before disassembling the

transceiver.

DO NOT

open the transceiver until the transceiver is

disconnected from its power source.

DO NOT

them slowly and smoothly.

DO NOT

short any circuits or electronic parts. An insu-

lated tuning tool MUST be used for all adjustments.

DO NOT

keep power ON for a long time when the trans-

ceiver is defective.

DO NOT

transmit power into a signal generator or a

sweep generator.

ALWAYS

connect a 50 dB to 60 dB attenuator between

the transceiver and a deviation meter or spectrum ana-
lyzer when using such test equipment.
