Follow these steps to install crys-
tals.
1. Remove the battery pack and
the antenna.
2. Use a Phillips screwdriver to
remove two of the screws on
the battery guide
shown. Then loosen the other
two screws on the battery guide
plate about 4 full turns. (This
makes it easier to reinstall the
back cover later).
Note: You do not need to loosen
or remove the battery contact
plate's two screws.
3. Pull up the rubber plug covering
the MIC and EAR jacks to
expose both jacks.
Caution: PUSH TO TALK on the
side of the transceiver is under
spring tension, and it might
come loose when you remove
the back cover in the next step.
To avoid losing PUSH TO TALK
12
plate as
and its spring, place your hand
over PUSH TO TALK while
removing the back cover.
4. Use a Phillips screwdriver to
remove all four screws from the
transceiver's back cover. Then,
while holding PUSH TO TALK
with one hand, carefully remove
the back cover.
5. Install or replace the new crys-
tals in the sockets. Be sure to
install the receive and transmit
crystals in the correct sockets as
shown.
6. Replace the back cover and
secure it with the four screws.
