Section 2 - Basic operation and key functions
All possible keys and their functions are listed here. Note that some of the keys may not be available, depending on your Lowrance VHF radio model.
| 6 Key handset mic | |
Key: | Function: |
|
VOL / | Volume and Power |
|
Turn clockwise to power on. Continue to turn until a comfortable volume is reached. VOL / will also adjust the settings of an external speaker, if connected.
SQL | Squelch or Threshold Level |
| Sets the threshold level for the minimum receiver signal. Turn fully counterclockwise |
| until random noise is heard, then turn slowly clockwise until the random noise |
| disappears. Make another 1/4 turn clockwise for best reception in open sea conditions. |
| In areas of high noise (eg. close to large cities) reception may improve if sensitivity is |
| reduced. Either turn SQL slowly clockwise or use the LOCAL setting. See section |
16 / 9 | Priority channel |
| Also on the handset mic. Press to cancel all other modes and to tune into the priority |
| channel. Press again to return to your original channel. The default Priority Channel is |
| CH16. |
| For US models: To make Channel 09 the priority channel, hold down 16/9 until a |
| beep sounds and 09 is displayed. |
DISTRESS | Send a DSC Distress Call |
| DSC must be active and an MMSI must be programmed. See Section 7. |
| Lift the red cover door then press and release DISTRESS to show the DISTRESS menu. |
| Select the category you want to transmit. Hold down DISTRESS for about 3 seconds |
| to transmit. |
| The DISTRESS key can also be held down continuously to transmit an “undefined” |
| category Distress call. |
| See Section 8 for more information about distress calls. |
