SECTION 2. 10
As can be seen, the POWER SAVE current is very low. Although the
screen is on and the keyboard responsive to any key depression, this
is the condition in which HUNTER is expected to be most. of the time.
A typical application example might be a salesman using HUNTER for
order entry purposes at a number of customer's premises and returning
to base for communication.

Exanple of Power Consumption
The day is 7.5 hours long, during which he makes five calls. At each
call he uses HUNTER for 40 minutes for stock checking and order entry
purposes. The communication time takes 15 minutes, with a further 5
minutes left powered up.
Of the 40 minutes use at each call, only 5 minutes is considered
'operation' since most of the time HUNTER is waiting for keyboard
entry.
