Maintenance and cleaning
To avoid electrical shocks, do not allow liquid to penetrate the housing.
Clean the housing at regular intervals using a dry cloth without any cleaning agents. Do not
|
use abrasive, scouring or solvent-based cleaners.
Blow loose dirt particles from the IR lens. Brush of any remaining dirt using a fine lens brush.
|
Safety
If the housing is opened, remember that some internal capacitors may still hold
potentially lethal voltages even after the device has been switched off.
In the event of errors or unusual operation, stop using the device and ensure that
it cannot be used until it has been carefully checked out and repaired.
Changing the batteries
If the device is not to be used for a long time, remove the batteries and store the device in a place
that is neither too hot nor too humid.
Do not leave used batteries in this device. Even anti-leakage batteries can corrode and release
chemicals which can damage both the device and your health.
Procedure
When the battery working voltage is too low, the battery
|
symbol is shown in the LCD; the batteries must then be
replaced.
The Testboy TV 325 requires two Micro LR03/ AAA
®
|
batteries or identical types.
Turn off the device
|
Open the battery compartment (1) by pushing the battery
|
compartment cover downwards and then folding it away
from the handle.
Replace the batteries with new ones of the same type, fold
|
the cover back in place onto the handle and push it
upwards.
Do not dispose of batteries in normal household rubbish. Use an authorised local
collection point!
