PZ3 Low Impedance Amplifier
Battery Status LEDs
Battery Level:
Eight LEDs indicate the voltage level of the selected battery bank.
These LEDs can be found on the front of the PZ3 amplifier by the heading Level.
When the battery is fully charged, all eight LEDs will be lit. When the battery
voltage is low, only one green LED will be lit. If the voltage is allowed to drop
further, the 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 amplifier with the charging cable disconnected. Connecting the PZ3
charger will simultaneously charge both batteries. Ensure that the three-position switch
is in the OFF (middle) position while charging the PZ3.
Charging Indicators
LEDs are also used for each bank to indicate which bank, 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 bank 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
