DUAL WATCH — guard channel and another channel 10. DUAL WATCH - guard channnel and another channel The dual watch function allows you to keep watch on coast guard channel stored in the memory and another channel. You should store a coast guard channel in the memory number “0” for this function. For example, coast guard channel is CH13 in the memory and another channel is CH20; Channel Indication CH20 CH 13 CH20 CH 13 CH20 ••• Receiving Time (sec.) 1 0.15 1 0.15 1 Procedure v -f [1] Select the channel you want to watch along with coast guard channel stored in the memory. [2] While pressing and holding down the PHIFt key, press the key. The indication DW appears on the display. The coast guard channel in the MEMO 0 and channel selected are watched at intervals of 0.15 second and 1 second, respectively. Further, the LCD alternately displays CH13(MEMO 0) and the channel selected. DW CH16 I [3] To escape from the dual watch mode, hit any key or press the PTT switch on the handset. Tip • When a signal is present on coast guard channel in the memory number “0”; (D The receiver locks on coast guard cahnnel and ignores the other channel. ® Five seconds after the signal on coast guard channel has gone, the receiver reverts to dual watching again. • When a signal is present on the channel being watched; Keep dual watching before escaping from this mode. 1-14 11. SCANNING 11. SCANNING The receiver scans a channel mode (USA, WX, etc.) in ascending channel order, stopping when a signal above a certain level is received. The receiver employs multiple watch; 1-cycle mode and endless mode. One of two modes is available by presetting the jumper wire inside the transceiver. Note that the factory setting is endless mode. Mode Function Multiple Watch [1-cycle mode] The receiver scans in the selected mode and CH16 is always watched between channels. It terminates scanning when all channels are watched. (ex) Scan starts on CH12 in INTL mode. start end 12^16——*16 — 88 — 16^01 — 16——*>16 — 11 Multiple Watch [Endless mode] The receiver continuously scans in the selected mode and CHI6 is always watched between channels. (ex) Scan starts on CH12 in INTL mode. [- 12 - 16- 13 ---28 - 16 — 60 -■••- 16 — 88n >—16*-11—..............................-16-02 — 16 / 11 .......

SCANNING Scan Stop Mode The receiver offers two modes to stop scanning when it finds a signal, hold or lock. • HOLD Mode When the receiver finds a signal on a channel other than CH16, it stops scanning and starts dual watching between CH16 and that channel. After dual watching for * times, it reverts to multiple watch. (ex) Set the DW quantity for 3 times.

Further it keeps watching on CH16 for five seconds. After that, the receiver reverts to multiple watch. 1-16 11.

GENERAL 1. GENERAL DSC is an acronym meaning Digital Selective Calling. Digital Selective Calling is a digital distress calling system in the MF, HF and VHF frequency bands used by ships for transmitting distress alerts and by coast stations for transmitting the associated acknowledgements. For distress and safety operation, simplex frequency is used. The VHF DSC frequency is 156.525MHz (channel 70). Channel 70 is designa...
