7.2 Resetting the System

To minimize these effects and enable you to get the best possible
performance from your Raymarine equipment, guidelines are
given in the installation instructions, to enable you to ensure min-
imum interaction between different items of equipment, i.e.
ensure optimum Electromagnetic Compatibility (EMC).
• Always report any EMC-related problem to your nearest Rayma-
rine dealer. We use such information to improve our quality stan-
dards.
• In some installations, it may not be possible to prevent the equip-
ment from being affected by external influences. In general this
will not damage the equipment but it can lead to spurious resetting
action, or may result in momentary faulty operation.
There are two types of reset available for the DSM250:
• Factory Reset: This resets all values back to their original fac-
tory settings.
WARNING:
The factory reset clears the sonar depth offset and speed and
temperature calibrations.
• Power-On Reset: When you turn the DSM250 off and on again,
all previous settings are retained except for those listed in the fol-
lowing table, which are reset to the factory default:
