Operating the Instrument on External Power
When the instrument is connected to AC power, you can use 
the power supply as a continuous power source. In this way, 
you can test for long periods of time without depleting the 
battery.
To operate the instrument using AC power, refer to Figure 2 
and do the following:
1
Connect the power cord to the external AC adapter 
charger.
2
Connect the AC adapter charger to the power jack on 
the instrument’s side panel.
3
Turn on the instrument.
You can also power the instrument and charge it at the same 
time with the (optional) auto lighter charger. Plug one end 
of the auto lighter charger into the instrument and the 
other end into a vehicle power outlet.

The EtherScope
 
Network Assistant is designed to be used as a 
dispatched or desktop network test device. The instrument is 
shipped with a removable yellow holster that provides more 
protection for dispatched tasks.
The instrument is also packaged with a stand for use on a 
desktop. To access the stand, remove the yellow holster. 
Then, pull the stand out from the bottom of the instrument 
(see Figure 2). 
A stylus for navigating the user interface is stored in the right 
side panel near the green On/Off button.
