Unit
Description
The VHF 725e is a 5 watt marine VHF communications transceiver in a convenient handheld package.
A keypad located on the front of the unit provides onehand control of communication features. The knobless design allows push-button Squelch and Volume adjustment. A single button press provides a manual Squelch Override function. Tri-Watch monitoring mode allows simultaneous monitoring of emergency channel (16), Call channel and a working channel programmed by the user. The channel 16 key allows you to toggle between emergency and working channels.
A 1” high by 1-3/8” wide LCD display provides indication of all features and functions of the VHF 725e. The scan feature allows the operator to select up to 10 channels for continuous monitoring in any combination of U.S.A., Canadian, and International bands.
Call Channel programming allows you to select and program a channel for regular conversation for instant access by pressing the Call key. The high/low key toggles the transmitter power level from between five watts and one watt. When held for more than one second, it locks and unlocks the “Key Lock” function to prevent inadvertent changing of unit settings and modes.
The power key turns the unit off and on and, when pressed briefly after the unit is powered on, enables the display backlighting feature and illuminates the keys on the front of the unit.
Small size and light weight characterize the portability of the GARMIN VHF 725e.

Eleven keys provide access to all of the unit’s features and functions. When any key (except the PTT key) is pressed, the unit will acknowledge by emitting a single beep confirmation tone. Some keys have dual functions and those keys on the front of the unit are illuminated when the display backlighting feature is active.
Power/Backlighting Key - This key turns on the unit when pressed and released, and turns the unit off when pressed and held for more than one second. Briefly pressing and releasing the power key when the unit is on will activate the backlighting feature and will last for five seconds after the last key is pressed.
Channel Up and Channel Down Keys - Pressing these CH arrow keys sets the operating channel. Pressing these keys while the Squelch key is pressed and held, sets the squelch threshold level.
Call Channel Programming/Call Key - Pressing this key for longer than 1 second after selecting a channel from one of the channel bands will store that channel as the calling channel to be accessed whenever the Call key is pressed. You can program a Call channel for each of the three bands (USA/Canadian/International).
NOTE: Selection of appropriate call channels is based on a working knowledge of available channels and their designated uses.
Volume Increase and Volume Decrease Keys - Pressing the plus and minus keys increases or decreases the volume of received transmissions and audio tones.
Memory Key - Pressing this key after selecting a channel places that channel into the scanning memory. Pressing this key when a channel is stored in memory (as indicated by the MEM icon on the display) will remove the channel from memory. A maximum of ten channels can be stored in memory.
Scan Key - Pressing this key starts the scanning of channels entered into memory. Pressing this key while scanning disables the scan feature while retaining the selected channels in memory.
U/I/C (USA/International/Canadian) Frequency Bands Key - This key allows the operator to select from the three channel bands. Pressing and releasing the key sequences through the three bands. The band selected is displayed on the LCD screen.
Channel 16 and Tri-Watch Key - Pressing this key once will monitor channel 16 (the emergency channel). Pressing again will return to the last used regular channel. Pressing and holding the key for more than 1 second will activate TriWatch which monitors channel 16 and the programmed Call channel for the currently monitored band and a working channel..
PTT (Press To Talk) Key - This Key allows the operator to transmit over those regular band channels that permit transmission. Press and hold the key to talk and release to receive.

H/L Power Key
Squelch Key - This key breaks the squelch (unmutes the audio) when pressed and held. It is also sed to set the squelch threshold (the level at which only strong signals can be received). The squelch threshold is set by pressing and holding the squelch key while using the UP/DOWN keys to adjust the squelch level from 0 to 9. At level 0, all signals can be heard, while at level 9, only the strongest signals can be heard. Adjusting the squelch level eliminates weak, unwanted signals, as explained on page 17.
H/L (High/Low) Power Key - This key toggles the transmitter power level from High (5 watts) to Low (1 watt) when pressed and released. It also locks the keypad when pressed and held for more than one second.. The Power key, PTT key, backlighting key and the Squelch key still function in the Lock mode. Locking the keypad prevents inadvertent changing of channel settings and feature modes.
