Voice Synthesis Unit; Vhf Converter - Kenwood R-5000 User Handbook Manual

VOICE SYNTHESIS UNIT

The VS-1 Voice Synthesis Unit option provides a synthesized voice announcement of
the currently displayed frequency. The announcement is made through the speaker (or
headphones) whenever the VOICE switch is depressed, and it can be either in English or
Japanese. Visually impaired operators can then hear which frequency they are tunned to.
This option is installed in a shielded case on the top left hand side of the chassis next to
the AVR board. Two cables with a 3 pin connector and an 8 pin connector are usually stored in
this opening. The 3 pin connector goes to the connector labeled J01 on the VS-1 board. The 8
pin connector goes to the connector labeled J02 on the VS-1 board. The board is then vertically
secured with two screws. Switch S1 on the VS-1 option selects English or Japanese language,
and VR1 adjusts the volume level of the announcement.

VHF CONVERTER

The VC-20 VHF Converter option allows the R-5000 to receive VHF frequencies of 108-
174 MHz. These frequencies cover the civilian aviation band of 108-136 MHz, the federal
government band of 136-144 MHz, the amateur "2 meter" band of 144-148 MHz, and the public
safety band of 148-174 MHz. FM mode is usually used in this area except for AM in the aviation
band. The VC-20 has its own antenna jack on the rear panel. This option allows the R-5000
owner to monitor local public safety communications and keep in touch with what is happening
in their home town as well as across the globe.
This option mounts on brackets over the top of the IF board in the receiver. Be careful
when removing the top cover and disconnect the speaker wires for easy access. Be careful of
the delicate wires in this area. The mounting brackets, which are included with the option,
should be attached to the sides of the VC-20 first. Next remove the plug from the hole under the
VHF ANT label on the rear panel. Slide the VC-20 into the receiver rear-end first to make sure
the antenna jack aligns with the hole. Secure with the four screws provided through the R-5000
rear panel. Secure the VC-20 mounting brackets to the two small mounting tabs on the chassis.
These tabs are located on both sides of the IF board. Three cables with connectors (2 pins, 7
pins, and 8 pins) are bound together with beaded bands. Remove this band and connect them
to the VHF Converter. The 2 pin connector goes to connector location 2, the 7 pin connector to
connector location 3, and the 8 pin connector goes to connector location 4 on the front of the
VC-20. Plug the coaxial cable connected to the VHF Converter to the connector marked VIF
near the front left corner of the IF board. Reconnect the speaker and replace the top cover,
taking care not to pinch wires, etc.
To use this option you must press the HF/VHF button on the front panel to switch back
and forth between frequency ranges. Note that with this option installed you have two more
VFOs for VHF, bringing the total to four for the receiver. The antenna selection switches ANT1
and ANT2 do not function in VHF mode.
