Tone Sender: ET300/ ET400/ ET500/ET720/ET800
The ET is a tone sender which is connected to the end of the cable/line/wire/
wire/wire pair that is to be searched/tested (connectivity depends on product).
Voltage resistance in case of accidental connection to external voltage:
ET300 /ET400/ET720/ ET800: 120 V AC
ET500: 350 V AC
Switching on
AfterpressingtheON/OFFkey,atoneisaudibletoconrmpower-up(ET720/
ET800only)andtheALTandSOLIDLEDslightupbriey.Forallotherver-
sions, depending on the position of the three-stage slide switch, the following
LEDsareusedasswitch-oninformation:TONEmode=ALTLEDashes,
DATA mode = DATA LED lights up in a dim green, CONT mode = CONT LED
ashesbriey.
Switchingo󰀨
Press the ON/OFF button for longer than 1.5 seconds. The ALT and SOLID LEDs
lightupbrieyanditswitcheso󰀨;ET720andET800soundashutdowntone.
TheETswitcheso󰀨automaticallyafter90minutes.Ifitisneededforlonger,
the ON/OFF button has to be pressed twice within 1 second after the unit is
switchedon.Toconrmthatthetimeoutoverridemodehasbeenactivated,
he SOLID LED ashes briey. If TONEmode and SOLID are active, this
function is taken over by the ALT LED. The ET720/ET800 will sound a short
conrmationtone.
Low Batt – battery voltage monitoring
When the device is switched on and the battery falls below a voltage of ap-
prox.6V,theSOLLEDashesbrieythreetimesevery60secondstoindi-
