Warranty

CES Wireless Technologies Corp., (CES), warrants this product to be free from defects in material and workmanship for one
year from the date of shipment. If such malfunction occurs, it will be repaired or replaced (at our option) without charge for
materials or labor if returned to the factory. This warranty does not apply to parts damaged due to improper use- including
accident, neglect, unreasonable use, and improper installation - or to unauthorized alterations or modifications of the equipment.
It does not extend to damage incurred by natural causes such as lightening, fire, floods, or other such catastrophes, nor to
damage caused by environmental extremes, such as power surges and or transients. It does not extend to microprocessors if is
determined that the failure of a micro is due to static damage, application of improper voltages to the unit, or other problems not
related to circuit design. In such case or in the case of a desire to update the micro to a different version of software, such
request must be specified in writing, and there will be a charge agreed upon by both parties.

This product is warranted to meet published specifications and to operation as specified only when properly installed in radio

equipment which complies with US FCC specification and the applicable radio manufacturer’s specifications. CES WIRELESS
is not responsible for any operational problems caused by system design, outside interference, or improper installation. A
qualified two-way radio technician or engineer must complete installation and programming of this CES WIRELESS product.

Equipment for repair must be returned to the factory, freight prepaid, only with prior authorization. Please call 407-679-9440
for an RMA number. A brief letter describing the nature of the defect should be included with the merchandise. Repair by other
than CES WIRELESS will void this warranty. In-warranty merchandise must be shipped, freight prepaid, to CES WIRELESS.
CES WIRELESS will return the repaired or replaced equipment prepaid to purchaser, within the United States. Outside the US
the customer must pay freight.
This warranty applies to the original purchaser of the equipment only. CES WIRELESS is not liable under this warranty, or any
implied warranty, for loss of use or for other consequential loss or damage experienced by the purchaser. Some states do not
permit the exclusion or limitation of implied warranties or consequential damages. This warranty provides special legal rights,
and the purchaser may have other rights that vary from state to state.

Model 710 Manual

GENERAL DESCRIPTION

The CES Model 710 DTMF Encoder Microphone is engineered specifically for mobile radio applications. Whether
used on SMR trunked systems, conventional telephone interconnected shared mobile radio systems, or in dedicated
single-user radio systems, your new 710 series microphone will enhance the utility of your mobile communications.
It's automatic ANI (Automatic Number Identification) and automatic-dialing features will be a great convenience to
you when using your mobile radio system and while operating a motor vehicle. Standard features in the Model 710
microphone include:

 Automatic push-to-talk transmitter keying

 Level matching to interface with any transceiver

 "Store and send" of manually dialed numbers

 Automatic "off-hook" and "on-hook" ANI's

 Automatic dialing of up to 21 digit numbers

 Durable back lighted silicone rubber keypad

 Precise crystal controlled tone generation

 Autodialing of "4th column" tones (A, B, C, D)

 Automatic microphone muting

 Audible DTMF sidetone

 Auto-encode of two different 21 digit ANI's

 Auto-dial and auto-ANI speed changes and delays

 Auto-dial pauses, with or without PTT

 Rugged urethane extreme temperature coil cord

 Ten year non-volatile EEPROM memory (no battery backup required)

INSTALLATION

Your CES Model 710 DTMF Encoder microphone requires filtered +10 to +15 VDC to power it's audible sidetone,
keypad illumination, and microprocessor. The 710 is available with factory installed mating connectors for many
popular transceivers. The connectors are configured to receive the required operating power at the radio microphone
jack.

Some transceivers may not already have a provided voltage source output available at the microphone jack. In this
case, a minor modification will be necessary and can be accomplished by a two-way radio technician. Locate a
switched and filtered source of +10 to +15 VDC within the radio and connect it to an unused terminal on the
microphone jack. If you are using a microphone with a factory-installed connector: use the terminal associated with
the microphone Blue wire. In the case where no spare or unused connection is available, determine an appropriate
function that is otherwise not going to be used, such as "handset audio", or other.

It is important to utilize a filtered voltage source for the microphone operation. If alternator whine or other ignition
noise is experienced on the transmitted audio, another voltage source should be located and used. In severe cases, a
filter available from an appropriate supplier should eliminate the problem.

If your microphone was ordered without an installed connector, then install a connector on the Model 710
microphone cord as follows:

Cable Wire Color Function

BLUE + 12 VDC
RED Push-To-Talk (logic low)
WHITE TX Audio Output
BLACK CTCSS Hang Up (logic low)
SHIELD Audio/Analog Ground
YELLOW Power & Logic Ground

Jumper JP2 - Microphone Low/Power Ground Isolation Jumper

Jumper JP2 is used to isolate the microphone low in the microphone from the logic and power ground. If the voltage
supplied to the microphone is not well filtered (or if noise is experienced on transmit), or for transceivers that
require separate ground returns, remove (cut) jumper JP2.

CTCSS Hang Up is a logical function that will normally provide an off-hook (open-circuit) or on-hook (closed­circuit) to the radio for CTCSS "monitor", or other applications. This requires a grounded hang-up clip for the
microphone.

For applications where an open circuit is required for an on-hook condition (off-hook=closed circuit), a logic
inverter option is available.
