APPENDIX D: CHANGING THE LNT MODULE BATTERY
The LNT Module uses a lithium coin CR2023 battery that will last about 5 years and is installed with the original LNT Module assembly. After you replace the battery, you will need to recalibrate the telescope’s sensors and reset the time and date. You will need a new battery. Also, you may use Meade’s optional Atomic Time Update Module, although this is not necessary.
To replace the battery:
1.Remove the top alignment screw cap/long bolt from the LNT Module. See Fig. 34.
2.Remove the side alignment screw cap/long bolt from the LNT Module. Take note that there are two springs inside the LNT. One spring sits between the top and bottom of the unit. The second spring is on the side of the unit that rests between the bottom and the top sections. One long bolt passes through the top spring and the other long bolt passes through the side spring. Set the springs aside as you will need to replace it later in this assembly . See Fig. 35 and 36.
Important Note: Note there is some wiring inside the LNT Module. Be careful not to pull on the wiring. If it is necessary to move the wiring aside, do so carefully.
3.Carefully lift the top section of the unit from the bottom section. Do not remove the bottom section or disassemble the rest of the unit.
4.Remove the old battery. Note the spring.
5.Insert the new
6.Replace the top spring in place and the LNT Module cover.
7.Replace the top bolt and tighten the cap to a firm feel.
8.Hold the side spring in place with your fingers and slide the spring between between the top and bottom sections. The spring should line up with the mounting holes for the side long bolt. Slide the long bolt through the side hole, then through the spring and finally through the bottom of the LNT Module and tighten to a firm feel.
9.Next you will need to recalibrate the LNT Module sensors. Select Calibrate Sensors from the Setup: Telescope menu.
10.Press ENTER. The telescope will automatically find North, detect level and the tilt of you telescope, and calibrate the sensors.
11.Next, follow the instructions included with the Atomic Time Update Module optional accessory to reset the clock.
OR
Enter the date and time manually using the Date and Time options in the Setup menu.
