Tono-Pen XL Body
Avoid any shock or excessive vibration which will damage the unit.
Clean with a non-abrasive, dry cloth.
CAUTION: DO NOT IMMERSE TONO-PEN XL BODY IN FLUIDS. THIS WILL
CAUSE DAMAGE TO THE ELECTRONICS AND VOID THE WARRANTY.
Battery Replacement
The batteries need replacing when multiple beeps sound and “Lob”
appears on the LCD upon depressing the activation switch. Occasion-
ally, a noticeable slowing in the calibration check process or in activating
the instrument for taking measurements may suggest that the batteries
need replacing.
Note: Replace the battery with P/N 230570.
Note: Always replace both batteries. Do
not mix used and new batteries in
the instrument. Reichert OCU-CEL
XL batteries are recommended.
Note: The instrument will not function
properly when mercury batteries
are used.
Replace the batteries using the procedure described in the Battery
Installation section. Remove the battery cover and then remove the bat-
teries using the Stylus. Refer to Figure 9.
Note: One end of the Stylus has a thin pointed end. Insert this end into
the holes on the back of the pen to remove the batteries.
If the instrument is not to be operated for an extended period of time,
remove both batteries. This will avoid possible damage to the instrument
due to battery leakage.
