Operating Instructions

oSetting the “channel end” scanning range (if funtion SF8 ac- tivated)

Call up function SF 14 using the MDE key. The following displays appear :

Top line

SF 14

Bottom line

CS channel number

Using the kHz (steps of 1) or MHz (steps of 10) switch, select the end channel at which the scan function is to stop. Store the end channel by pressing the STO key.

oEntry of password to interlock the equipment configuration

Call up the SF 15 function using the MDE key. The following display appears :

Top line

SF 15

Bottom line

0

Set any 4-digit numerical code using the kHz (steps of 1) or MHz (steps of 10) switch. Store the numerical code by pressing the STO key.

NOTE

As soon as a password is given an 0 appears in the bottom line when the service mode is called up. The numerical code must then be input using the MHz or kHz switch. If the portable VHF station detects a false numerical code, it automatically switches to the last mode. If the password is to be erased or changed, this is done by calling up the service mode using the old password. The SF 15 function is then chosen and either an 0 is entered everywhere or the changed numerical code is entered.

NOTE

•Due to the carrier controlled squelch, the audio output is quieted with a certain delay after removal of an adequate RF-signal from the re- ceiver input. This delay causes noise appearing in the audio output for some time. The presonce of this unwanted short time noise can be eliminated by activating the squelch fast mode in the service mode. With the squelch fast mode activated, it can occur that parts of a received message are blocked out and are not audible when the RF input signal is very weak.

oJamming of transmit button

The portable VHF station is fitted with a protective circuit to protect against jamming of the transmit button or a short circuit on the key supply line. For continuous transmissions exceeding two minutes the protective Circuit automatically switches from transmission to reception. This avoids the switched channel being blocked.

In the event of a fault, this is only possible after the short circuit has been cleared or the transmit button released.

NOTE

•In order to be able to continue transmitting even with the transmit button jammed, the portable VHF station must be switched off and then back on again. After that the portable VHF station then continu- es to operate in the transmit mode for a further two minutes.
