PLEASE NOTE:

NexStar Handsets can be prone to error messages due to voltage fluctuations from the use of rechargeable or low powered batteries. This can be rectified by "flashing" the handset (full details are given on Celestron’s website) and can be mitigated by using new lithium batteries or the use of Power tanks, such as the Sky-Watcher 7 or 17Ah Power tank.
