Turning On/Off Your Transceiver Rotate VOLUME knob to turn the transceiver on or off with an indicating voice of click. And adjust the volume to a comfortable level. Adjusting Squelch Rotate SQ knob to adjust squelch threshold level. Squelch is used to eliminate static and background noise and allows for silent operation of the TM-886 until a transmission is received. If the squelch is too high, only the strongest transmissions can be heard, and when too low, intermittent static and noise are heard. Selecting High/Low Power or Lock keypad Press and release this key to toggle the transmit power between high and low. When the unit is operating at low power, “Lo” appears on LCD and “Hi” appears on LCD when operating at high power. You also can lock your radio keypad to avoid accidental pressing of keys by activating the key lock. Pressing and holding H/L/LOCK button until key lock icon will appear on LCD if it is enabled. The function is effective to all other knobs/keys except PTT and H/L/LOCK buttons. Selecting a Channel Press the ▲/▼ (UP/DOWN) button to scroll through the available channels. Note: Not all channel numbers are available in INT bands. Transmitting and Receiving Press and hold the Push-To-Talk (PTT) key to transmit on the selected channel, then release to receive. The TX indicator appears while transmitting. Selecting a Weather Channel (If Available) The US National Oceanic and Atmospheric Administration (NOAA) broadcasts continuous weather reports and severe weather alerts, as needed. If so equipped, your TM886 is programmed to receive10 NOAA weather channels and sound an alarm if a weather alert is received. Press and release the WX/BAND button to enter Weather mode. The WX indicator appears. Press Channel ▲/▼ (UP/DOWN) button to change the WX channel 1 through Channel 10. Press and release WX/BAND button again to return to normal operation. Note: 1. Weather broadcasts can only be heard in the North America. 2. The TM886 can receive these broadcasts only if the unit has been upgraded by the distributor to use WX Channels. 3.
