Powering Down
1. When powered down using the CZ-command, the H-ADCP still draws up to 30µa, but wakes
up periodically (every 8 to 12 hours) for a few seconds to maintain RAM.
2. This command should be used whenever batteries have been installed and you do not send
commands to start a deployment. If you do not use the CZ-command, the H-ADCP will draw up
to 50 milli-amps of current. A new battery will be discharged in a few days.
3. Performance and testing commands (i.e. AF, PA, PT, RB, and RY) override the battery saver
functions. For example, using the RY-command to recover data from the H-ADCP while on
battery power will disable the automatic power saver mode. If a CZ-command is not used after
all data has been recovered, the H-ADCP will remain in the command mode. TRDI recommends
disconnecting the batteries and using the AC power adapter while testing or recovering data.
