Installation
To ensure a secure connection of an antenna cable's mini-UHF plug to a
radio's mini-UHF jack, their interlocking features must be properly
engaged. If they are not properly engaged, the system will loosen.
NOTE:
Applying excessive force with a tool can cause damage
to the antenna or the connector (e.g., stripping threads,
deforming the collar or connector, or causing the
connector to twist in the housing opening and break).
Motorola recommends the following sequence to ensure proper
attachment of the system (see Figure 3-10):
Figure 16 Mini-UHF Connection
1. Make sure that there is sufficient slack in the antenna cable.
2. Make sure that the collar of the antenna cable plug is loose and does
not bind.
3. Slide the collar back against the flange. Insert the antenna cable
plug's pin fully into the radio jack, but do not engage the threads.
4. Ensure that the plug's and jack's interlocking features are fully seated.
Check this by grasping the crimp on the cable jack, rotating the cable,
and noting any movement. If the features are seated correctly, there
should be NO movement.
5. Finger-tighten the antenna cable plug's collar onto the radio's jack.
6. Give a final tug, by hand, to the collar, and retighten by hand as firmly
as possible.
7. Use the rubber-coated pliers to grip the plug's knurled collar, then turn
clockwise to tighten the collar. It should take 1/4 turn or less. Turning
counterclockwise loosens the collar.
NOTE:
Overtightening the collar can damage the connector and
the radio.
For radios equipped with telephone interconnect, a "PHON" button is
included with the order. If the customer wishes to utilize this feature, pry
out the black plug at the control unit position shown in Figure 17, then push
the PHON button into its place.
