4 Battery replacement and troubleshooting
This section of the manual describes the steps you should take when you believe the Datawell
Buoy Finder 4A is operating improperly or when the batteries are empty.
The instructions are divided into two categories:
•
Battery power and replacement.
•
Antenna, signal strength and noise.
If none of the steps described in those sections solve your problem, contact the Datawell Service
Department listed at the end of this manual.
4.1 Battery power and replacement
The Buoy Finder 4A 4 runs on four 1.5 V AA type batteries. The batteries are placed in the
battery compartment at the back panel, see Chapter 2.
When the batteries are empty this is shown as follows:
The Buoy Finder 4A does nothing or switches off automatically after a short time.
Display is not lit, no audio is heard via the internal speaker when adjusting the speaker volume.
If any of these signals is available, battery power is OK. If not, replace the batteries by
simultaneously pulling and depressing the ends of the drawer containing the batteries.
The choice of batteries has a significant influence on the operating time. Therefore only alkaline
types are recommended. Some alkaline batteries are designated as ‘high-power’ or ‘high drain’
types. These batteries are optimized to deliver their energy in a relatively short time span and
are especially suitable for the Buoy Finder 4A.
NOTE:
The specified battery life is measured using alkaline batteries during continuous operation at
room temperature. Low operating temperatures will shorten the battery life while interrupted
usage (allowing the battery to ‘recharge’ it self) will lengthen the battery life.
