Solder the connector to the main board, and cut M3 6mm bolt the connector left over. ! use 16mm bolts if K8099 used with B8099 FINAL TEST Connect the 12Vac to the board, if all works well, the displays should light. Check the user manual for further set-up... - Page 10 Configuring and setting CONFIGURING AND SETTING YOUR CLOCK 50Hz AC: OK 50Hz AC: OK 50Hz AC: OK Apply 9-12VAC. The clock will display '50' or '60' for 3s, depending on the AC power frequency (Hz) in your area. This indicates that the zero cross detection part of the clock circuit is working fine.
- Page 11 Configuring and setting Show this hour Show this hour Show this hour To save energy and extend tube life, the unit allows you to blank the display for certain periods (e.g. at night, while you are absent, etc...) The digits on the left hand side of the separator indicate the hours (00 to 23).
