3-3-2. CW mode

Set MODE keys to CW and set the Meter switch toALC.

ALC PWR SWR

c::::m:1:::J

Placing the Standby switch to send and depressing the CW key will cause the radio to transmit.

Transmission is also possible when in the SEMI or FULL break-in mode by simply depressing the key, with the Standby switch in the REC position.

(b) Full-automatic break-in

Depressing the CW key will automatically place the transceiver into the transmit mode. Releasing the CW key will return the radio to receive immediately enabling reception between characters.

Caution:

The TL-922A/922 linear amplifer is not designed for full break-in type operation. Attempting to use this accessory in the FULL break-in mode cause damage to occur to the linear amplifier.

Adjust the CAR control until the meter deflection is within the ALC zone.

On occasion an electronic keyer may be used that has no method of producing a continuous trans- mit condition. In order to obtain a continuous car- rier for tuning simply place the Standby switch to the SEND position.

1.The FM power output may fluctuate if running less than full output.

2.Ensure that an antenna with a low 5WR is used. The T5-4405 provides several protection circuits, continually loading into an antenna with a high 5WR (3 to 1 or greater) will eventually cause damage to the final amplifiers.

3.The PWR meter reading may not be accurate with high SWR values. Use a good antenna for the most accurate readings.
