Repeat to advance to the next group. • The selectable channel groups differ, depending on the transceiver version. for 1 second U.S.A.
BASIC OPERATION ❏❏Selecting Channel 16 Channel 16 is the distress and safety channel. It is used for establishing initial contact with a station, and for emergency communications. While in the standby, you must monitor Channel 16. qqPush [16/C] to select Channel 16. ww Push [CH/WX] to recall the channel that was displayed before selecting Channel 16. Push ❏❏Selecting Call channel Each channel group has a Call channel.
4 BASIC OPERATION Receiving and transmitting CAUTION: Transmitting without an antenna can damage the transceiver. qqPush [Y] or [Z] to select a channel. • When a signal is received, “ ” appears. wwHold down [PTT], and then speak into the microphone. •“ ” appears while transmitting. • You cannot transmit on Channel 70.
BASIC OPERATION Adjusting the squelch level Squelch is a function that allows the audio to be heard only while receiving a signal that is stronger than a set level. You can adjust the squelch threshold level. A higher level blocks weak signals, so you receive only stronger signals. A lower level allows you to hear weak signals including noise. 4 Monitor function The Monitor function momentary cancels the squelch function. You can check for weak signals. ➥ Hold down [MONI] (VOL/SQL) for 1 second.
4 BASIC OPERATION Volume Loud function You can temporary maximize the volume level with a simple operation. This function electronically locks most keys to prevent accidental changing of the channel and function access. ➥ While holding down [VOL/SQL], push [Y]. ➥ Hold down [ ON or OFF. • The volume level is set to the maximum level. • Push [VOL/SQL] and [Y] again to turn OFF the function.
BASIC OPERATION quaQuake Water Draining A function Water in the speaker grill may muffle the sound coming from the speaker. The AquaQuake Water Draining function removes water from the speaker grill, by generating vibrating the speaker. ➥ Hold down both [SCAN] and [Hi/Lo] for 1 second. • A low vibration tone sounds for 10 seconds to drain water, regardless of the volume level setting. • This function also stops when a key is pushed.
5 SCAN OPERATION (All except the HOL version) Scan types You can find ongoing calls by scanning the Favorite channels. Before starting a scan, you need to: • Set the desired channels you want to scan as Favorite channels (Page 15). (Only Favorite channels are scanned.) • Set the desired scan type to "Normal (default)" or "Priority" in the Set mode (Page 18). NORMAL SCAN A normal scan sequentially searches through all Favorite channels.
5 SCAN OPERATION (All except the HOL version) Setting Favorite channels Starting a scan You can quickly recall often-used channels by setting them as Favorite channels, which can be independently assigned to each channel group. qq Hold down [U/I/C] (CH/WX) for 1 second to change the channel group. Repeat to advance to the desired group. qq Hold down [U/I/C] (CH/WX) for 1 second to change the channel group, if needed. Repeat to go to the next group.
