INITIAL INSPECTION
Carefully unpack the instrument and accessories and inspect for
damage. Compare received parts with items on the packing list. If
any parts or materials are damaged or missing, contact YSI Customer
Service at 800-897-4151 (+1 937 767-7241) or the authorized YSI
distributor from whom the instrument was purchased.
BATTERY INSTALLATION
The instrument requires 2 alkaline C-cell batteries. Under normal
conditions, the average battery life is
425 hours at room temperature
without using the back light. A battery symbol
will blink in
the lower, left corner of the display to indicate low batteries when
approximately 1 hour of battery life remains.
To install or replace the batteries:
1. Turn the instrument off and flip over to view the battery cover
on the back.
2. Unscrew the four captive battery cover screws.
3. Remove the battery cover and remove the old batteries if
necessary.
4. Install the new batteries, ensuring correct polarity alignment
(figure 1).
5. Place the battery cover on the back of the instrument and
tighten the four screws. Do not over-tighten.
The Pro1020 cannot communicate to a PC via a ProComm
communications saddle.
