1.5. CARE AND MAINTENANCE
Perform only the processes discussed in this manual. Never attempt to take the
Escape203 apart or service it yourself (i.e. open the case or remove the buttons).
Protect your Escape203 Electronic Altimeter from shocks, extreme heat and
prolonged exposure to direct sunlight. When not in use the Escape203 should be
stored in a clean, dry environment at room temperature when not in use.
The Escape203 Electronic Altimeter can be wiped clean with a lightly moistened (use
warm water) cloth. Apply a mild soap to clean stubborn stains or marks.
Avoid exposing the Escape203 Electronic Altimeter to strong chemicals like gasoline,
cleaning solvents, acetone, alcohol, adhesives, and paint. These will damage the
unit's seals, case and finish.
Make sure the area around the sensors (bottom front side of the instrument) is kept
free of dirt and sand. Never insert any objects into the sensor openings.
1.5.1. Battery Replacement
The Escape203 Electronic Altimeter operates on a three-volt lithium cell. Type: CR
2450. The maximum life expectancy is approximately 2-3 years.
A low battery-warning indicator is activated when 5-15 percent of the battery capacity
is still available. When this occurs we recommend replacement of the battery.
Extreme cold weather will activate the low battery-warning indicator. Though the
indicator is activated, the battery may not need to be replaced due to this condition. In
temperatures above 10°C (50°F), if the low battery warning indicator is showing, the
battery will need to be replaced.
To replace the battery:
1. Turn the Escape203 Electronic Altimeter over to view the backside.
2. Insert a coin in the coin slot located on the battery compartment cover.
