System Program error
■Problem
A System Program error has occurred.
If this error occurs, the BHT beeps five times (for 0.1 second per beep) and then turns itself off.
■Solution
Contact your nearest dealer.
Battery voltage has lowered.
Low battery indication—Level 1
■Problem
When the power is turned on or off or during ex- ecution of program (System Mode or application), the battery output level has dropped below a specified lower level limit.
If low battery is detected, the BHT displays this message for approx. 2 seconds and beeps three times (for 0.1 second per beep). After that, it will resume previous regular operation.
■Solution
The service life of the battery cartridge will expire soon, requiring replacement or recharge.
If the BHT is loaded with the rechargeable battery cartridge, replace or charge it. (For the charging procedure, refer to Chapter 5, Section 5.5.)
If the BHT is loaded with the dry battery cartridge, replace the dry cells.
