Scan Operation
Scan Types
Scanning is an efficient way to quickly locate signals over a wide frequency range. The transceiver has a priority scan setting and normal scan setting. In addition, the "Auto scan" function is available for scanning. This function can be activated simultaneously, depending on the settings on the SET mode (p. 17).
Priority Scan
Priority scan searches through all tag channels in sequence while monitoring Channel 16. When a signal is detected on Channel 16, scan pauses until the signal disappears; when a signal is detected on a channel other than Channel 16, scan becomes dualwatch until the signal disappears.
Normal Scan
Normal scan, like priority scan, searches through all tag channels in sequence. However, unlike priority scan, Channel 16 is not checked unless Channel 16 is set as a tag channel.
Set the tag channels (scanned channel) before scanning. Clear those tag channels which are not needed or inconveniently stop scanning, such as digital communications.
Choose priority or normal scan on the SET mode (p. 17).
Setting Tag Channels
For more efficient scanning, add desired channels as tag channels or clear the tag for unwanted channels. Non-tag channels will be skipped during scanning. Tag channels can be assigned to each channel group (INT, USA*¹, ATIS*²) independently.
1. Select the desired channel group (INT, USA*¹, ATIS*²) by pushing [DIAL] for 1 sec., if desired.
2. Select the desired channel to set as a tag channel.
3. Push both [▲] and [▼] for 1 sec. to set the displayed channel as a tag channel. "TAG" appears in the function display.
4. To cancel the tag channel setting, push both [▲] and [▼] for 1 sec. "TAG" disappears.
Clearing all tag channels in the selected channel group: While pushing and holding both [▲] and [▼], turn power ON to clear all tag channels in the channel group.
Starting a Scan
Set the priority scan function, scan resume timer and auto scan function in advance, using the SET mode (p. 17).
1. Select the desired channel group (INT, USA*¹, ATIS*²) by pushing [DIAL] for 1 sec., if desired.
2. Push [SCAN•DUAL] to start priority or normal scan. "SCAN" blinks in the function display. "16" appears on the sub channel readout during priority scan.
3. When a signal is received, scan pauses until the signal disappears or resumes after pausing 5 sec. according to scan resume timer setting. (Channel 16 is still monitored during priority scan.)
4. Push [▲]/[▼] to check the scanning tag channels, change the scanning direction or resume the scan manually.
5. To stop the scan, push [SCAN•DUAL]. "SCAN" disappears. Pushing [PTT], [16•C] or [DIAL] also stops the scan.
Dualwatch/Tri-watch
Description
Dualwatch monitors Channel 16 while you are receiving another channel; tri-watch monitors Channel 16 and the call channel while receiving another channel.
(Diagrams show Dualwatch and Tri-watch simulations)
- If a signal is received on Channel 16, dualwatch/tri-watch pauses on Channel 16 until the signal disappears.
- If a signal is received on the call channel during tri-watch, tri-watch becomes dualwatch until the signal disappears.

Optional Swivel Belt Clip
MB-86 Contents
- Belt clip: 1
- Base clip: 1
- Supplied screws: 2
Attachment
1. Screw the base clip to the back of the transceiver using the two screws (supplied), as shown below.
2. Clip the belt clip over your belt and insert the transceiver.
3. Once the transceiver is locked in place, it swivels as illustrated below.
Detachment
Turn the transceiver upside down in the direction of the arrow and pull out from the belt clip.
CAUTION: HOLD THE TRANSCEIVER TIGHTLY, WHEN HANGING OR DETACHING THE TRANSCEIVER FROM THE BELT CLIP. Otherwise the transceiver may not be attached to the belt clip or swivelled properly if the transceiver is accidentally dropped and the base clip is scratched or damaged.
Optional Speaker-Microphone
HM-125 Descriptions
(Diagram shows speaker-microphone with labels: Alligator type clip, PTT switch, Microphone, Speaker)
Attachment
Insert the speaker-mic connector onto the [MIC/SP] connector and carefully screw it tight, as shown in the diagram below. Be careful not to cross thread the connection. Set the triangle mark to the front side.
(Diagrams show detaching and attaching the speaker-mic connector)
CAUTION: Attach the speaker-microphone's connector securely to prevent accidental dropping, or water intrusion in the connector.
IMPORTANT: KEEP the transceiver's [MIC/SP] connector cap attached when the speaker-microphone is not in use. Water will not get into the transceiver even if the cover is not attached, however, the terminals (pins) will become rusty, or the transceiver will function abnormally if the connector has become wet.
Note: The microphone is located at the top of the speaker-microphone, as shown in the diagram above. To maximize the readability of your transmitted signal (voice), hold the microphone approx. 5 to 10 cm from your mouth, and speak in a normal voice level.
