7 REV (Reverse) Switch

7 REV (Reverse) Switch

This switch is used to check repeater input Signal. By depressing the switch, the TX and RX frequencies are reversed. To reverse the frequencies once again, set the transceiver in transmit mode while holding the switch in the depressed Position.

8 TONE Switch

Tone oscillator switch which makes 1750 Hz FM wave when pressed in FM mode only.

9 LOW POWER Switch

Set this switch to LOW Position and the FM transmit out- put is reduced to about 1 Watt. Use the switch for FM mode only. (This switch has no effect on SSB and CW mode.)

10 NB (noise blanker) Switch

Use this switch during SSB or CW Operation to reduce pulse ignition type noise from automobiles, etc. This is very useful when receiving weak Signals.

(This switch will not function in FM mode.)

11 Meter switch

By using this switch, the meter functions as an S meter, ALC meter or CEN (Center) meter.

Note: When the switch is set to the ALC/CEN Position during FM transmission, the meter functions as an RF meter but the meter pointer deflection will be slightly deviated.

1 2 V O X S w i t c h

This switch is used for voice operated transmission on FM or SSB, or semi-break-in Operation on CW (set to VOX posi- tion). lt is also used in combination with the standby switch or microphone PTT switch (set to MAN position).

13 Standby Switch

Set this switch to the down Position for reception, and to the up Position for transmission . By pressing the microphone PTT switch, the unit automatically shifts from reception to transmission.

14 POWER Switch

The power to the unit is turned ON by setting the power switch to the up Position, and turned OFF at the down posi- tion.

15 MIC Connector

Connector for microphone up/down input and PTT circuit.

1 6 PHONES Jack

This headphone jack allows use of a set of headphones of 8-l 6 ohms impedance. Connect KENWOOD headphones HS-4, 5 or 6 available as an optional accessory.

A stereo headphones may also be connected.

17 MODE Switch

In FM - CH mode, the VFO frequency is switched in 20/10 kHz Steps.

In FM, LSB, USB or CW mode, the VFO frequency is swit- ched in 20/200 Hz Steps.

1 8 PRIO. M S w i t c h

Depress the PRIO. M 191 switch to call out the memory channel 9CH. Depres the [IO] switch to call out the 1 OCH. These memory channels are preset to 145 . 000 . 0 and 433.000.0, respectively, but can be set to any desired fre- quencies.

19 TIGHT lever

This lever is used to increase the torque of the VFO dial knob so that the knob can not be rotated by external shock.

20 F . STEP Indicator

This indicator will light when the F. STEP switch (32) is ON.

21 Tuning Knob

Turn this knob to select your desired frequency.

22 FUNCTION Switch

This function switch selects one of the following transceive functions. Normally It should be set to the “A” or “B” Position.

A-R: For VFO A Operation during reception and for VFO B Operation during transmission.

A:For VFO A Operation.

8:For VFO B Operation.

8-R: For VFO B Operation during reception, and for VFO A Operation during transmission.

23 MEMORY Selector

This switch selects any of the memory channels l-l OCH. Use the switch when frequencies are stored in the memory channels or the stored frequencies are called out in the ON Position of the RM switch.

The channels (9) and ( IO] are common to the priority chan- nels [9] and [IO] . These channels are preset to 145.000.0 MHz and 433.000.0 MHz, respectively.

2 4 SSB MIC

This control adjusts the gain of the microphone amplifier during SSB Operation. Adjust it so that the ALC meter does not deflect beyond the ALC Zone.

2 5 R I T Indicator

This indicator will light when the RIT switch (33) is ON.
