current altitude setting to match current conditions; each depression of
POWER will increase the altitude setting by 500 feet until 9999 has been
reached, at which time the setting will return to 0 and begin increasing
again.
6) To save the changes and return to ranging mode, let the unit sit idle
for at least 20 seconds until an automatic power-down occurs, or simply
press and hold MODE for at least 1 second. To continue through the
Quick Set Menu and manipulate another feature, press and release
MODE until the appropriate icon is displayed.
