Page 35: Configuring Product Families
CONFIGURING PRODUCT FAMILIES The PACS Deck Unit can be configured to work with EdgeTech’s LF, MF, and MFE, series releases and transponders. The following procedures outline how to configure the PACS for each. 4.1 LF-BACS Operation Configuration This procedure describes how to configure the PACS for operation with EdgeTech’s LF Releases and Transponders: 1. - Page 36 Press the yellow ENT key to set the lower range gate. 17. With EdgeTech LF acoustic releases, because the standard TAT is 13mS, a lower range gate of less than 35 meters is not attainable. To select a lower range gate, use the left and right arrows. The lower range gate will increment or decrement 25 meters with each key stroke, holding an arrow key in will cause the value to scroll up or down.
- Page 37 to set it. Sound speed can be set in 1 meter per second increments, holding an arrow key in will cause the value to scroll up or down. 20. After setting the sound speed, the next Ranging Menu item will ask if the user wants to set either manual Ranging Mode or repetitive Ranging Mode.

A M I L I E S 4.2 MF Operation Configuration This procedure explains how to configure the PACS for operation with EdgeTech’s MF series Releases and Transponders: 1. Turn the Deck Unit on, without connecting the transducer. It takes approximately two seconds for the PACS to power up, it will beep twice and the display will become legible when it is ready. - Page 39 Press yellow ENT key to set the lower range gate. 19. With EdgeTech MF Acoustic Releases, because the standard TAT is 100mS, a lower range gate of zero meters is achievable. To select a lower range gate, use the left and right arrows. The lower range gate will increment or decrement 25 meters with each key stroke, holding an arrow key in will cause it to scroll.
- Page 40 S E C T I O N 4 : O N F I G U R I N G R O D U C T A M I L I E S speed can be set in 1 meter per second increments, holding an arrow key in will cause the value to scroll up or down.

Page 41: Mfe Operation Configuration
4.3 MFE Operation Configuration This procedure configures the PACS unit to work with EdgeTech’s MFE series Releases and Transponders: 1. Turn the PACS on; it is not necessary to connect the transducer. It takes approximately two seconds for the PACS to power up, it will beep twice and then the display will become legible when it is ready. - Page 42 Press the yellow ENT key to set the lower range gate. 17. With EdgeTech MFE acoustic releases, because the standard TAT is 100mS, a lower range gate of zero meters is achievable. To select a lower range gate, use the left and right arrows. The lower range gate will increment or decrement 25 meters with each key stroke, and holding an arrow key in will cause the value to scroll up or down.
- Page 43 23. Unless the user has a special underwater unit equipped with telemetry, disable telemetry. Use the left and right arrow to make a selection, and use yellow ENT key to disable telemetry. 24. After telemetry is disabled, the Ranging Menu will return to the start of the range menu. 25.

Page 45: Maintenance
If the PACS is going to be stored for a prolonged period of time (over 6 months) the battery pack should at minimum, be unplugged. However, EdgeTech recommends removing the battery from the unit and stored separately. The Battery should be discharged to approximately 15.0 volts prior to storage. -
