Please Note: Keypad firmware v4.17 addresses some issues that primarily relate to customers with eastern longitudes and fixes some bugs that were created in earlier attempts to address these issues in v.4.15 and v.4.16. However, we recommend that all customers in the western hemisphere also upgrade their keypad firmware to version 4.17 at this time. We have repaired a bug in v4.15 that only affected older keypads with serial numbers of 1490 and earlier (purchased before April, 2002). When v.4.15 was loaded into these older keypads, the real-time clock stopped functioning. There was no damage done to the clock, and clock function could be restored by simply re-loading v.4.12, or now by loading v.4.17. Version 4.16 fixed the clock problem, but had a separate issue with occasional random freeze-ups of the keypad during initialization, especially when resuming from Reference Park 1. We are now very confident that these issues have been resolved, but if you have a clock related problem or a keypad freeze-up after loading v4.17, please contact us at the e-mail address below:
