specific voltage value matched with output power shown above in 1-2. Unit: V
Notes:
Please switch off the equipment when changing the SIM card.
The equipment can be
turn on when SIM card is correctly inserted and the cables are well connected. If you
can not make calls or receive text messages, please check the connection of the socket
in GPRS module, possible overdue GSM card bill, or the loose connection between
antenna and other cables. If you can make calls but can not receive the messages, which
might indicate weak signal and strong disturbance, please check if the antenna and
feeder of GPRS are in near distance with output port and feeder of the repeater, which
should be set far from repeater antenna. If the GPRS doesn’t work after being se up by
the steps above, or the signal is too weak and interference is too strong, an extension
cable with length of 10 meters should be added to the output interface of GPRS module.
Try to keep the GSM antenna away from repeater transmitting antenna. Use waterproof
tape to cover the connectors. If the signal is normal, there is not need to add 10 meters
extension cables, which will cause attenuation to GSM signal.
If there is no GSM mobile signal nearby, GPRS function is not available.
It takes about 2 minutes for the GPRS to get started. Please check short message later
on. It is normal that the monitor module may fail to work properly in 10 seconds while
repeater is sending message. It is internal protection mechanism. Everything will be
operated properly when the message is done.
