4.Loosen the four screws on the cover of the cell phone enclosure and remove the cover, to view the signal strength. The signal strength is indicated by the number of dashes across the bottom of the cell phone display. The more dashes the greater the signal.

6.2.2.2Reliable Communications

In order to ensure reliable communications between the sampler and the host computer, it is absolutely essential that the host computer is equipped with a Cellular Compatible modem. The modem on the host computer must support the “MNP.10ED” protocol. Computers equipped with modems that do not support this protocol may be able to connect to the sampler but will not be able to maintain reliable connections.

6.2.2.3 Cellular Modem Scheduling

Note: If the Cellular Modem Scheduling is disabled and the sampler is connected to a cell phone rather than a land line, the sampler will not be able to answer any incoming calls.

Note: If Modem Power is disabled, the Cellular Modem Scheduling prompt will not appear.

With Cellular Modem Scheduling enabled, both the modem and cell phone power will simultaneously be turned off and on at user defined intervals to conserve battery power. If Cellular Modem Scheduling is disabled the sampler will assume that a land line is available and that the cell phone is not connected to the sampler. With Cellular Modem Scheduling disabled (and the sampler on battery power) the sampler will leave the modem turned off until a call is received on the land line.

If the sampler is on ac power or the battery voltage is over 14.5 volts, the power to both the cell phone and modem will constantly be on regardless of whether Cellular Modem Scheduling is enabled or not.

If the sampler is configured to call a pager for alarms and the alarm condition is met, the sampler will still call the pager even if modem scheduling is disabled. In this situation the cell phone and modem will temporally be powered back up again to allow the sampler to call the pager and transmit the alarm code. However, as soon as the alarm code is transmitted, the power to the cell phone and modem will again be turned off.

1.To enable Cellular Modem Scheduling, Modem Power must be enabled.

2.Enable the Cellular Modem Scheduling using the CHANGE CHOICE key.
