    Test and Program Timer (Timer Installations Only) Manually set the Timer on and make sure the CTM is able to receive a call. Manually set the Timer off and make sure the CTM does not answer a call. Finally, program the Timer to enable the CTM. Consult the instructions sup- plied with the Timer for details.
  • Page 23 HARGE UDGET When using the CTM in a solar/battery-powered station, one must limit the power drawn by the CTM. The means limiting the time that the CTM is on, enabled to receive calls, and limiting even more severely the duration of calls. The worksheets below enable you to calculate the charge drain per day and the charge gain per day (from the solar panel).
  • Page 24 Line D (CTM Transmitting) The CTM draws an additional 1300 mA (1.3A) when transmitting. Charge Drain per Day Example The example worksheet shown below illustrates the power drain for a GroWeather, using the Timer to turn the cell-phone on for six four-minute peri- ods each day.
