13 INITIAL POWER-UP TEST
1. At the radio’s main waterproof (HFB-type) fuse holder installed near the vehicle battery, insert the
15-amp AGC-type fuse that was included with the radio’s DC Power Cable.
2. Tie and stow all fuse holders at this location to prevent excess vibration/movement.
3. Carefully reconnect the vehicle’s battery ground cable.
4. If not already, temporarily connect the mobile antenna cable from the vehicle-mounted mobile
antenna to the female TNC RF connector on the rear panel of the radio. This is a temporary
connection until test procedures in Section 14 are complete.
5. If the radio is equipped with the GPS receiver option, permanently connect the antenna cable from the
GPS antenna (or mobile/GPS combo antenna) to the female SMA connector on the rear panel of the
radio. The male SMA connector on most GPS antenna cables has a 5/16-inch hex collar, so the use of
a wrench of this same size is normally required for tightening. However, some may have collars with
only knurled surfaces, so a standard wrench or torque wrench cannot be used. In either case, do not
over tighten the connector and do not
twist the cable when tightening.
6. If the installation is wired so the vehicle’s ignition key/switch turns the radio on and off, turn the
switch to the Accessory or Run position.
7. If the control head is not already powered up, do so by rotating its on/off/volume control clockwise
out of the detent position. For the HHC-731, press the on/off power button located just above the
display.
8. Verify the control head/hand-held controller has powered-up by observing its display. If the display is
not functioning, refer to Section 8.2.1 as necessary.
Unlike many mobile radio products, the radio powers-up to the state of last control.
As long as the software configuration parameters have been loaded, successful installation is almost
immediately realized:
After a short boot-up sequence, the control head/hand-held controller displays login information
and/or a talk group.
If no errors are displayed, the installation is most-likely properly wired.
If an error is displayed, recheck all cable connections, verify all fuses are properly installed, and
verify battery power on the load side of the fuses, etc. If problems persist, contact the Technical
Assistance Center (see page 26).
Consult the Operator’s Manual for operational information.
Refer to Section 14 for performance test information.
