[ toc ] 3. Adjusting the Right Ascension Lock
After a period of time, it is possible that the R.A. lock (7, Fig. 3) of the LX200 will not tighten sufficiently due to internal wear of the clutch mechanism. In such an event, remove the R.A. lock lever using one of the hex wrenches supplied with the telescope. Then, with a pair of pliers, tighten the shaft protruding outward from the drive base until you cannot easily rotate the fork arm in R.A. (Take care in this operation not to damage the cosmetic finish of your LX200). Replace the R.A. lock lever so that its handle points straight out from the cross-bar connecting the fork arm.

The LX200 Power Panel houses the back-up replaceable battery (2, Fig. 28) for the clock and calendar and a replaceable standard 1.0 amp slow blow fuse (1, Fig. 28). The long-life lithium battery (Panasonic CR2032 3 volt or Duracell DL2032B) is stored behind the front panel of the Drive Base. The battery does have to be changed every few years, and is done so by unthreading the four phillips-head screws that secure the Front Panel to the Drive Base. Then with a thin flat-head screw driver, lift the small coin-size battery out of its' holder. The new battery simply slides in place. See the illustration below: The 1 amp slow blow fuse will sacrifice itself to protect the LX200 electronics in the event that the telescope is prevented from completing a GO TO function (e.g. the tube runs into something that keeps it from slewing). The illustration below shows the location of the fuse.

[ toc ] 5. Factory Servicing and Repairs
Meade LX200 7", 8", 10", and 12" models have been designed and manufactured for years of trouble-free operation and repairs should rarely be necessary. If a problem does occur, first write or call our Customer Service Department. Do not return the telescope until you have communicated with us in this way, since the great majority of the problems can be handled without the return of the telescope to us. However, should the occasion arise that the instrument requires factory servicing, a Meade Instruments Customer Service Representative will issue a Return Goods Authorization (RGA) number and give you full instructions on how to use it. Product returned without the RGA may greatly delay any servicing or repairs. When telephoning or writing, please explain the exact nature of the problem so that we may offer a prompt remedial procedure. Be sure to include your full name, address, phone and fax numbers where you can be reached. Should you live outside of the United States, contact your Authorized Meade Distributor from where you purchased the instrument. You can reach the Meade Instruments Customer Service Department either by mail, phone, or fax at: Meade Instruments Corporation, 6001 Oak Canyon, Irvine, CA 92620- 4205, telephone (714) 451-1450, or telefax (714) 451-1460. Outside of the U.S.A., dial your International Access Code, then 1, then the ten digit number above in the 714 area code.
