(5) RF Xmit Power
The SRM6200E-SLC offers users the ability to modify the Transmission Power of the radio modem. There
are 10 power settings available (1-10) which are roughly linear. Therefore a setting of 10 is full power or (1 Watt) and 1 is
10% power (or 100 mw). The following guidelines should be followed when setting the RF Transmission Power:

(6) Remote Security
With option 6 the user may disable the radio modem’s security so it will accept a call from any other SRM6200E-SLC.
The default setting is 0 where security is enforced (the caller’s call book number must be in the Remote’s Call Book).
With a setting of 1 security is disabled.
(7) RTS to CTS
This setting is not applicable to the SRM6200E-SLC and should not be changed from the factory setting (the factory
setting is 0)
(8) Retry Time Out
The Retry Time Out parameter allows the use to determine when a remote will drop a connection to a master or repeater
in multi-point mode. The default setting is 255, meaning that if one packet in 255 from the Master is sent successfully to
the Remote it will maintain a link. The lowest setting is 8, at which a remote will drop a connection much faster.
The Retry Time Out parameter is useful when a multi-point system is used with a moving master or remotes. As the link
gets weaker, a lower setting will allow a remote to drop it’s link and search for a stronger connection.
While intended primarily for multi-point systems, the Retry Time Out parameter may also be modified in point-to-point
systems. In point-to-point mode the Retry Time Out should not be set to a value of less than 151.
(9) Lowpower Mode
The Lowpower Mode is not applicable to the SRM6200E-SLC. This setting should not be changed.
(A) High Noise
Use the menu to indicate if the modem will be operated in an environment with a high degree of radio noise and
interference.
With a setting of 1, the rejection of interference is improved, at the cost of reduced range and/or throughput.
(B) MCU speed
This setting is factory set to 1 (high speed) and should not be changed.
