Viking VM600 Mobile Radio Operating Manual 4-11
General Operation
4.1.10 Preventing Vehicle Battery Discharge
In the standby mode (power on, not transmitting), radio power consumption is relatively
low. Therefore, you can probably leave the radio ON for one or two days without
operating the vehicle and the battery should not become seriously discharged. However, if
the outdoor temperature is low enough to significantly decrease battery capacity, the radio
should be turned OFF when not in use.
Since power consumption is significantly higher when transmitting, it is good practice to
have the vehicle running while transmitting. This ensures that optimum power is being
delivered to the radio and that the battery does not become discharged.
4.1.11 Cleaning the Control Head
The radio Control Head requires periodic cleaning, depending upon the operating
environment.
You will need a soft brush of a size that can access all exposed areas of the Control Head.
You will also need a vacuum cleaner that is portable enough to easily access the Control
Head.
To clean the Control Head:
1
Use the brush to remove the bulk of sand and dust from the Control Head.
Ensure that this is done in an environment that does not allow other equipment to be
affected by the removed sand and dust. If necessary, use the vacuum to collect material as
it is removed
.
2
When the bulk of sand and dust is removed, use the brush to clean the interface joint
between the buttons and Control Head plastic.
3
Position the vacuum nozzle two inches (or more, as required) from the face of the
Control Head. Use the brush to remove any remaining sand and dust.
4
Repeat this procedure until the Control Head is completely clean.
