While synchronizing you may have sped the clock up or slowed it down by a full count Should you need to correct the seconds turn the rotary switch to the Set Hour clock setting position At the moment you de select the Live Sync position the clock will be split again at the time that was being displayed as you de selected Live Sync If necessary correct the seconds after turning the rotary switch to the Set Sec position After synchronizing the clock turn the rotary switch to RUN or at least as far as the Auto Print position to return to normal operation 12 TIMEWISE 650 OPERATION Automatic A Timewise 650 can automatically set the time in another 650 using a master slave communication protocol built into the instruments That is a Master Slave 650 previously aligned to the official time can insert that time into another Synchronizing 650 The automatic synchronizing procedure takes about two seconds and may be performed at any time To execute the synchronizing procedure you will need a synchronizing cable to interconnect two 650 s A standard stereo audio cable is used for this purpose Such a cable is readily available from Radio Shack as part number 42 2387 This 6 foot stereo audio cable two wire plus shield has the required 1 8 inch stereo miniature phone plugs at each end You may of course fashion your own synchronizing cable using 1 8 inch stereo plugs and three wire cable To do so just connect the thr

Print The 650 will immediately blank the display When the display is turned off in this manner the clock will run for only six more hours before completely shutting down Activating Print again or any other toggle position before the six hours pass will turn the back display on The normal 24 hour shut down wait period is then restarted NOTE By leaving the rotary switch in the Silent position the 650 consumes less energy about 15 pamps less current while it is shut down This can extend battery life an additional 2 months during storage NOTE Also note that for every five seconds the LCD backlighting pushbutton is depressed the batteries are drained the equivalent of one hour or more of normal operation If you use the backlighting a lot the batteries will have I gt gt to be replaced more often If you cannot see the LCD backlighting in the ark it is time to replace the batteries The 650 will run about 10 days on batteries that can no longer power the LCD backlighting TIMEWISE 650 19 OPERATION The Remote The Remote Split input provides a means of splitting the 650 via an Split Input external switch closure The remote split connector accepts an 1 8 inch p p miniature stereo phone plug Contact assignments for the connector are Shaft Ground connected to the negative side of the 6 volt supply Ring Remote split input held high to 5 3 volts with a 3KQ pull up resistor and connected to a CMOS input via a
