MAINTENANCE
To keep your Humminbird® VHF55S working properly, perform the following maintenance as
needed.
If your unit comes into contact with salt spray, simply wipe the affected surfaces with a cloth
dampened in fresh water. Do not use a chemical glass cleaner on the lens, as chemicals in the
solution may cause cracking in the lens. When cleaning the LCD protective lens, use a chamois
and non-abrasive, mild cleaner. Do not wipe while dirt or grease is on the lens. Be careful to avoid
scratching the lens.
WARNING: Never leave your VHF55S in a closed car or trunk; the extremely high temperatures
generated in hot weather can damage the electronics.
TROUBLESHOOTING
Before contacting the Humminbird® Customer Resource Center, please read the following section.
Taking the time to review these troubleshooting guidelines may allow you to solve a performance
problem yourself, and therefore avoid sending your unit back for repair.
NOTE: Do not attempt to repair the VHF55S yourself, as there are no user serviceable parts
inside, and special tools and techniques are required for reassembly in order to maintain the
waterproof integrity of the housing. Repairs should be performed only by authorized
Humminbird® technicians.
VHF55S Doesn't Power Up
If your VHF55S doesn't power up, refer to the Installation section, and make sure that:
• The Ni-MH battery pack is fully charged (14-15 hours).
• The battery pack or batteries are installed properly.
• If you are using six AA alkaline batteries, make sure they have a charge.
Correct any known problems, including removing corrosion from the battery terminals, or actually
replacing the batteries (if using alkaline) if necessary.
