10. Adding/Deleting Channels to/from Memory
Your VHF55S can store any channel (including private channels). The stored channels are the ones
scanned in the Memory Scan mode.
To add channels to memory:
1. During normal operating mode, use the Up or Down Channel keys to select the desired
channel for programming.
2. Press and hold the MEM key for 3 seconds. The Stored icon will appear, indicating that the
current channel has been saved in memory. Any number of channels scan be saved as
memory channels.
To delete channels from memory:
1. During normal operating mode, use the Up or Down Channel keys to select the saved
channel you wish to delete.
2. Press and hold the MEM key for 3 seconds. The selected channel will be deleted from
memory.
11. Scanning
Your Humminbird® VHF55S comes with three scan options:
• Normal Scan: If there are no channels in memory, the default is Normal Scan. In Normal
Scan mode, all channels in the channel set are scanned in sequence, assuming no
channels have been stored in memory. After the last channel number has been scanned,
the cycle repeats. Normal Scan automatically searches for transmissions on the channel
set being scanned. If a TX signal is received, the scan stops on the receiving channel as
long as it is present and the Scan icon is flashing. If the signal is lost for five seconds or
more, the radio resumes scanning.
• Memory Scan: In Memory Scan mode, only the channels that have been saved in
memory are scanned in sequence. After the last saved channel number has been
scanned, the cycle repeats.
• Priority Scan: In Priority Scan mode, you can scan all channels while alternately scanning
Channel 16 to make sure that you don’t miss distress or emergency calls.
To activate scan modes:
1a. Press and release the SCAN key when no channels are stored in memory to activate the
Normal Scan function. The Scan icon will appear on the LCD.
