12 78-9000-5020-0 Rev C

Active frequencies:

7573 577 Hz, 1 kHz, 8 kHz, 33 kHz, 82 kHz, 200 kHz

7573E (International) 577 Hz, 1 kHz, 8 kHz, 33 kHz, 82 kHz, 133 kHz

ALL indicates that the following active frequencies are transmitting simultaneously:

7573 577 Hz, 8 kHz, 33 kHz, 200 kHz

7573E (International) 577 Hz, 8 kHz, 33 kHz, 133 kHz

[T-4] Digital Display:

Indicator Flags: These ags coincide with the operational mode of the transmitter.

(From top left to bottom right) Fault Locate mode [T-2], Tone mode [T-2], Trace mode

[T-3], Ohm-meter [T-2], Voltage (at start up the transmitter checks for foreign voltage),

and the Output Level (no ag = normal output; ag = high output; ashing ag =

maximum output).

Digital Display: Indicates frequency, relative current, resistance, battery level and

voltage (if present on target).

[T-5] Output Level: Cycles output power level;

Normal=No Flag; High=Flag; Maximum=Flashing Flag (indicated in Digital Display [T-4])

NOTE: An external 12-volt power source is required to obtain Maximum Output level

and the 12-watt output level varies by frequency. Output is limited to 10 watts at 33

kHz and 1 watt at 82 kHz and higher using the direct connection method.

[T-6] Output Jack: Port for direct connect cables or Dyna-coupler cable.

[T-7] External Jack: Port to connect cigarette lighter adapter cable, or rechargeable

battery (2200RB). Input voltage level: 9-18 VDC. (Only on 5-watt and 12-watt

transmitters.)

H. Maximum Transmitter Output

An external 12V DC source is required for 12-Watt Output (Maximum setting) using a

12-watt transmitter. Connecting the rechargeable battery (2200RB) to the External Jack

[T-7] will provide this external source, or the cigarette lighter adapter cable (included

with high-powered units) can be used to connect the DC power from a vehicle’s battery

source to the transmitter’s External Jack [T-7].

Press Output [T-5] twice for maximum output power mode.

The indicator ag (in [T-4]) will ash when the transmitter is in maximum output mode.

Note: The external DC source does not charge the internal batteries.
