down into place.
• Maintain the Cover securely in place and turn it counter clockwise 10 degrees using the Cover tool (Fig. 126), or by pushing the lower
portion to the right while pushing the upper portion to the left using your fingers (Fig. 127).

Authorized Sherwood Dealer for a complete evaluation before attempting to use it.
TRT (Transmitter) Battery Removal
Locate the Battery Cover on the End of the Housing:
• Apply a coin to the recessed slot of the Cover and turn it counter clockwise out of the Housing (Fig. 128).
• Remove the Battery from the Battery Compartment and discard according to local regulations governing disposal of Lithium batteries.
Inspection
• Closely check all of the sealing surfaces for any signs of damage that might impair proper sealing.
• Inspect the Housingto ensure it is not cracked or damaged.
WARNING: If damage or corrosion is found, return your TRT to an Authorized Sherwood Dealer, and DO NOT attempt
to use it until it has received factory prescribed service.
• Remove the Battery Cover 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 threads of the Battery Cover and Housing for any signs of damage that might prevent proper threading.
• Closely examine the inside of the Battery Compartment for any signs of corrosion indicating entrance of moisture.
• If corrosion is found, return the TRT to an Authorized Sherwood Dealer, and DO NOT attempt to use it until it has received factory
service.
• If moisture is found, it is best to have the unit inspected and cleaned by an Authorized Sherwood Dealer.
TRT Battery Installation
• Lightly lubricate the new Battery Cap O-ring with silicone grease and install it onto the Battery Cap. DO NOT roll the O-ring over the
threads, instead stretch it slightly to work it down over the slotted end of the Cap into the groove at the base of the threads (Fig. 129).
NOTE: The TRT's O-ring must be a genuine Sherwood part that can be purchased from an Authorized Sherwood Dealer.
Use of any other O-ring will void the warranty.
• Place a new 3 volt, CR2, Lithium Battery (Duracell model DL-CR2 or equivalent) positive (+) side down into the Battery Compartment
with the negative end facing up/out (Fig. 130).
• Ensure that the Battery is properly oriented and the Cover O-ring is evenly seated around the Battery Cover.
• Carefully place the Battery Cover with Spring into the Housing and turn clockwise slowly by hand to ensure proper threading. Apply a
coin and tighten until secure. The outer surface of the Battery Cover should be flush with the outer surface of the Housing (Fig. 131).
