Initial Installation
External power control function
1.
Be sure the vehicle has a negative-ground, 12VDC electric system before installa-
tion. Connect the provided DC cable with fuse-holder directly to the battery (red
cable to the positive terminal) to minimize any possible ignition noise. Be sure the
vehicle has a large capacity battery as the use of a transceiver may overload the
electric system of the vehicle.
2.
In addition, if the optional ignition-key ON/OFF feature is desired, use the provided
ACC cable. Remove the cover by unscrewing 4 screws. Connect the ACC cable to
the ACC power jack (CN11) on the rear side of the circuit board unit, position the
outgoing cable as shown above, select the ACC switch (SW11) to ACC position and
reassemble the cover.
3.
When installing, be sure to disconnect the battery cables of the vehicle and be sure
the ignition key is in the “OFF” position. Connect the ACC cable to the ACC termi-
nal or ACC switch on the vehicle. Make sure the above sequence has been done
properly. Reconnect the vehicle’s electric system.
4.
If this option is selected, the unit can be turned on/off either manually or automati-
cally in accordance with the ignition key position.
A: When the ignition key is turned to ACC or ON (“run”) position with the unit left
turned ON, the unit will turn on automatically and turns OFF when the ignition
key is turned to the OFF position.
B: To manually turn the power on/off, leave the ignition key in the ACC position
and use the PWR switch on the unit. If the ignition key is in the OFF position the
unit won't turn on. The power consumption of this feature is about 5mA regard-
less of the ignition key position. For operation without this option, always use
the PWR switch to turn the unit on/off and set SW11 to “on”.
