BASIC OPERATION
I Adjusting the squelch level
The IC-M87 has a squelch even though there is no control knob for it. In order to receive signals properly, as well as for the scan to function effectively, the squelch must be adjusted to the proper level. q Push [SQL], then adjust the squelch level with [Y]/[Z].
- "SL" indicator appears. - There are 11 squelch levels to choose from: OP is completely open; 10 is the tight squelch level. - When no key is pushed for 5 sec. , the transceiver returns to normal condition.
I Lock function
This function electronically locks all keys (except for [PTT], [SQL] and [H/L·LOCK]) to prevent accidental channel changes and function access. to turn the lock function ON and OFF.
Appears while the lock function is used.
w Push [SQL] again to return to normal condition.
I Automatic backlighting
This function is convenient for nighttime operation. 19) Push any key except for [PTT] to turn the backlighting ON.
· The backlighting is automatically turned OFF after 5 sec. of inactivity.

I Call channel programming
The call channel key is used to select the default channel, however, you can program your most often-used channel in each channel group for quick recall. several times to select the desired channel group (INT, USA) to be programmed. to select the call channel.
· "CALL" and call channel number appear.
t Push [16·C] to program the displayed channel as the call channel.
· The call channel number stop flashing.
e Push [16·C] again for 3 sec. (until a long beep changes to 2 short beeps) to enter call channel programming condition.
· Call channel number to be programmed flashes.
r Push [Y]/[Z] to select the desired channel.

SCAN OPERATION
I Scan types
Scanning is an efficient way to locate signals quickly over a wide frequency range. In addition, an auto scan function is available for standby convenience. 18) 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. 13
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.

I Setting tag channels
For more efficient scanning, add desired channels as tag channels or clear tag channels for unwanted channels. Tag channels can be assigned to each channel group (INT, USA) independently. q Select the desired channel group (INT, USA) by pushing [DIAL] for 1 sec. , if desired. to set the displayed channel as a tag channel.
· "TAG" appears in the function display.
I Starting a scan
Set the priority scan function, scan resume timer and auto scan function in advance, using SET mode. 18) q Select the desired channel group (INT, USA) by pushing [DIAL] for 1 sec. , if desired. [. . . ] frequency deviation Marine PMR
