Notice
Changes or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including
interference that may cause undesired operation.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
-- Reorient or relocate the receiving antenna.
-- Increase the separation between the equipment and receiver.
-- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
-- Consult the dealer or an experienced radio/TV technician for help.
OEM integrators and installers are instructed that the phrase. This device contains
transmitter FCC ID: WA2ST-100M must be placed on the outside of the host.
Warning: Exposure to Radio Frequency Radiation The radiated output
power of this device is far below the FCC radio frequency exposure
limits. Nevertheless, the device should be used in such a manner that
the potential for human contact during normal operation is minimized.
In order to avoid the possibility of exceeding the FCC radio
frequency exposure limits, human proximity to the antenna should
not be less than 20cm during normal operation. The gain of the
antenna for Cellular band must not exceed 1 dBi. The gain of the
antenna for PCS band must not exceed 1 dBi.

the DTE. It also controls whether or not the DCE verifies the presence of dial tone when it first goes
off-hook to begin dialing, and whether or not engaged tone (busy signal) detection is enabled.
However, this setting has no effect on the operation of the W dial modifier, which always checks for
dial tone regardless of this setting, nor on the busy signal detection capability of the W and @ dial
modifiers. See Table.
