Priority Codes and Icons

The priority controls how the NOC delivers a forward message to the vehicle and how the driver is notified as described below.

Group messages are transmitted 12 times over 85 minutes, regardless of priority except for Extended Sleepy. Extended Sleepy group messages are transmitted 20 times over 72 hours. Return message priorities include  Normal and  Emergency. Emergency appears when the driver marks a return message as "Priority."

Priority	Transmission Attempts	Driver Notification
Normal	9 times over 35 minutes	Unit beeps once, message waiting light goes on.
Important	9 times over 35 minutes	Unit beeps once, message waiting light goes on. Optional remote devices are activated.
Sleepy	7 times over 18.25 hours	Unit beeps once, message waiting light goes on.
Sleepy-Important	7 times over 18.25 hours	Unit beeps once, message waiting light goes on. Optional remote devices are activated.
Extended Sleepy	10 times over 72 hours	Unit beeps once, message waiting light goes on. Note: TMCTs and MCTs do not support Extended Sleepy message priority. Any message sent to an MCT or TMCT with this priority will be transmitted as sleepy.
Attention	9 times over 35 minutes	Unit beeps three times, message waiting light flashes. Optional remote devices are activated and remain active until the message is read.
Emergency	10 times over 35 minutes	Unit beeps three times, message waiting light flashes. Optional remote devices are activated and remain active until the message is read.

Unlike other types of mobile units, MCP50 and OTIS units do not have a wakeup timer to scan for messages over long periods when the unit is off or out of coverage. If you send messages to MCP50 or OTIS-equipped vehicles select the Sleepy, Sleepy Important (Sleepy+), or Extended Sleepy message priority, because it attempts transmission over a longer period of time. For example, the Extended Sleepy message priority allows a message to be sent on a Friday and received on a Monday when the truck ignition is turned on after being powered off for the weekend.
