VHF/UHF PORTABLE RADIO
SECTION 4 - SERVICING
(4)
Device leads should always be in contact with a conductive material to avoid the build-up of static
charges.
(5)
Soldering iron tips, tools and metal parts of test equipment used in servicing must be grounded.
(6)
To avoid transient voltage spikes, devices must not be inserted into, nor removed from, circuits with
power applied.
(7)
Signals must NOT be applied to integrated circuits in the absence of power supplies to the devices.
(8)
Use conductive foam on work surfaces.
DIS-ASSEMBLY
Remove the Battery
(Refer to Figure 4.1)
(1)
Depress the spring-loaded battery latch to release the battery.
(2)
Slide the battery down the radio to disengage the retaining lugs.
(3)
Lift the battery away from the radio.
Figure 4.1 Removing the Battery
Remove the Antenna and On/Off/Volume Control Knob
(1)
Unscrew and remove the antenna.
(2)
Remove the lanyard ring (if fitted).
(3)
The On/Off/Volume control knob is a friction fit. Pull the knob from its spindle.
(4)
Remove the smart interface cover from the smart interface jacks and the antenna boss.
CAUTION
Metal Oxide Semiconductors (MOS) are used in this equipment; therefore
the following predictions should be strictly observed, otherwise the devices
may become damaged.
