Battery Installation
The Tono-Pen VET tonometer is shipped without the batteries installed.
The batteries need to be installed prior to using the instrument. The
Tono-Pen VET is supplied with four OCU-CEL 3.0 volt lithium manganese
dioxide batteries.
Note: The Tono-Pen VET unit will not function properly with mercury bat-
teries.
Note: It is recommended that Reichert OCU-CEL Batteries be used
when the batteries need replacement.

the end slot. After insertion, slowly push the stylus forward and pry
the cover up to remove. Refer to Figure 2.
CAUTION: CHECK TO BE SURE THAT THE BATTERIES ARE INSTALLED COR-
RECTLY. INCORRECT INSTALLATION COULD CAUSE SEVERE DAMAGE TO
THE ELECTRONICS AND VOID THE WARRANTY.
