• Remove the Battery Hatch O-ring and inspect it for any
signs of deterioration or deformity. DO NOT use tools to
remove the O-ring.
• To ensure proper sealing, O-ring replacement is highly
recommended each time a Battery is replaced.
• Closely examine the Battery Hatch and Housing for any
signs of damage that might prevent proper sealing.
• Closely examine the inside of the Battery Compartment for
any signs of corrosion indicating entrance of moisture into
the unit.
WARNING: If damage or corrosion is found,
return your ZEN to an Authorized TUSA Dealer,
and DO NOT attempt to use it until it has re-
ceived factory prescribed service.
Battery Installation
• Slide a new 3 volt type CR2430 Lithium Battery, negative
side down into the cavity of the compartment. Slide it in
from the left side (Fig. 114) and ensure that it slides under
the contact clip on the lower/right rim of the cavity.
• Lightly lubricate the new Hatch O-ring with silicone grease
and place it on the inner rim of the Battery Hatch. Ensure
that it is evenly seated (Fig. 115).
