RF Call Box Jumper Settings
Jumper Settings (CB19x–xx3 Models Only)
Carrier Level Detect
Activation of the RF Call Box circuitry relies on a carrier detect signal provided by the radio (HIGH or
LOW). The Carrier Detect Level is adjusted using Jumper P4. The factory setting for this jumper is the
LOW position. The Kenwood TK-3170 Series Radio provides a high output, which requires this jumper
to be moved to the HIGH position for proper operation. Please refer to Figure 11 on page 38 of this
manual for the P4 jumper location.
Private Line (TCS/DCS) Detection
In addition to the Carrier Detection, the activation of the RF Call Box circuitry may also require receipt
of an appropriate PL code, if programmed to do so. PL Detection is enable or disabled (ON/OFF) using
Jumper P9. Factory default is set to ON. This setting should be changed to the OFF position if PL is not
utilized in the RF operating system. This setting must match the other radios and Call Boxes in the
system.
Installing the Kenwood TK-3170 Series Radio
N OTE : The Kenwood TK-3170 Series Radio should be programmed and tested prior to installing
in the RF Call Box.
