8.Set Mode

8.3.5 Menu 5 Clock Shift Setting

In the unlikely event that you may hear a weak noise always on the same frequency, it

may be so-called a CPU-clock noise. Unfortunately this is due to the circuit-design of

this product and can't be eliminated, but can be moved away to another frequency.

1. SFT-OF is displayed on the LCD.

2. Rotate the dial to select the clock shift setting on and off.

8.3.6 Menu 6 Busy Channel Lockout Setting

This function restricts the PTT (transmit) operation.

1. BCL-OF is displayed on the LCD.

2. Rotate the dial to select the Busy Channel Lockout setting on and off.

When Busy Channel Lockout is set to on, transmission is possible only in the

following conditions (and isn't possible otherwise).

The alarm sounds if the PTT key is pressed when transmission is prohibited.

1) When no signal is being received (BUSY isn't displayed).

2) When the tone matches and the squelch is unmuted based on the Tone Squelch

setting conditions.

3) When the codes match and the squelch is unmuted based on the DCS setting

conditions.

BCL-OF BCL-ON

NOTE:

This function isn't a noise-blanker. Also, since not all noises are due to a CPU-

clock noise, the clock shift setting may not be effective.
