last LED will flash red. TDT recommends charging the battery before this flashing
low-voltage indicator comes on. While charging, the Level LEDs will flash green.
Charging the Batteries
Operate the preamplifier with the charging cable disconnected. Connecting the PZ2
charger will simultaneously charge both batteries. TDT recommends putting the three-
position switch in the OFF (middle) position while charging the PZ2.
Charging Indicators
When powered on, the PZ2 battery status LEDs are also used for each battery to
indicate which battery, if any, is charging. These LEDs are found next to the Level
LEDs by the headings -A- and -B-. A green indicator denotes the battery bank is
fully charged while a red indicator designates the battery is currently charging. When
the device is in operation (charger is not connected) the -A- and -B- LEDs are
not lit.
An external battery pack is also available to provide longer battery life for extended
recording sessions. See “PZ-BAT External Battery Pack for the PZ Amplifiers” on
page 6-23.
