Privacy Codes •
Your microTALK radio incorporates two advanced coded squelch
systems that can help to reduce interference from other users
on any given channel. CTCSS (Continuous Tone Coded Squelch
System) provides 38 privacy codes and DCS (Digitally Coded Squelch)
provides 83 privacy codes. This provides a total of 121 Privacy
Codes. Either system can be used on all channels, but both systems
cannot be used on the same channel at the same time.
To successfully communicate using a privacy code, both
the sending and receiving radios must be tuned to the same
channel and to the same privacy code system (CTCSS or DCS)
and privacy code number. Each channel will remember the last
privacy code system and number you select.
The privacy code 00 is not a privacy code, but allows all signals
to be heard on a channel that is set to 00 on both
the CTCSS and DCS systems.
Set CTCSS Privacy Codes •
To select a CTCSS privacy code:
1. After selecting a channel, press
the Mode/Power button until the CTCSS icon
appears and the small numbers next to the
channel number flash on the display.
If DCS is turned on at the channel selected,
the display will flash the
CTCSS icon and “OFF.” To switch from
DCS to CTCSS, press the Channel Up
or Channel Down button while the display
is flashing “OFF.” The display
will then show the small numbers flashing
and you will then be able
to proceed to step 2.
2. Press using the Channel Up or Channel Down
button to select a privacy code. You can hold the
Up or Down button for fast advance.
3. When your desired CTCSS privacy code is
displayed, choose one of the following:
a. Press the Mode/Power button to enter the
new setting and proceed to other functions.
b. Press Talk or Call/Lock button to enter the
new setting and return to Standby mode.
c. Do not press any buttons for 15 seconds
to enter the new setting and return to

FRS/GMRS Frequency
Allocation and Compatibility
Important: Please note that Cobra GMRS models with 15 Channels
may designate different channel numbers for the same frequency.
For example, a Cobra 15 Channel GMRS model would need to be
tuned to Channel 11 in order to communicate with a 22 Channel
GMRS tuned to Channel 15. Please refer to the chart below for
channel/ frequency number compatibility.
A = Channel No. for 22 Channel FRS/GMRS Models
B = Channel No. for 15 Channel GMRS Models
C = Type of Radio Service
D = Frequency in MHz
E = Power Output

Nothing Comes Close to a Cobra®
IMPORTANT NOTICE: FCC LICENSE REQUIRED •
MODEL CXT645:
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: COBRA IS NOT RESPONSIBLE FOR ANY CHANGES OR MODIFICATIONS NOT EXPRESSLY
APPROVED BY THE PARTY RESPONSIBLE FOR COMPLIANCE. SUCH MODIFICATIONS COULD VOID THE
USER’S AUTHORITY TO OPERATE THE EQUIPMENT.
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.
This device complies with Industry Canada licence-exempt RSS standard(s):
Operation is subject to the following two conditions: 1) this device may not cause interference, and 2) this device
must accept any interference, including interference that may cause undesired operation of the device.
Le présent appareil est conforme aux CNR d’Industrie Canada applicables aux appareils radio exempts de
licence. L’exploitation est autorisée aux deux conditions suivantes : (1) l’appareil ne doit pas produire de
brouillage, et (2) l’utilisateur de l’appareil doit accepter tout brouillage radioélectrique subi, même si le
brouillage est susceptible d’en compromettre le fonctionnement.
Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and
maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference
to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power
(e.i.r.p.) is not more than that necessary for successful communication.
Conformément à la réglementation d’Industrie Canada, le présent émetteur radio peut fonctionner avec une
antenne d’un type et d’un gain maximal (ou inférieur) approuvé pour l’émetteur par Industrie Canada. Dans le
but de réduire les risques de brouillage radioélectrique à l’intention des autres utilisateurs, il faut choisir le type
d’antenne et son gain de sorte que la puissance isotrope rayonnée quivalente (p.i.r.e.) ne dépassepas l’intensité
nécessaire à l’établissement d’une communication satisfaisante.
CXT645 has been approved by Industry Canada to operate with the antenna types listed below with the
maximum permissible gain and required antenna impedance for each antenna type indicated. Antenna types
not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly
prohibited for use with this device.
CXT645 a été approuvé par industrie Canada pour fonctionner avec les types d’antenne mentionnés
ci-dessous avec le gain permis maximum et l’impédance exigée d’antenne pour chaque type d’antenne
indiqué. Les types d’antenne non inclus dans cette liste, ou dont le gain est supérieur au gain maximal
indiqué, sont strictement interdits pour l’exploitation de l’émetteur.
The user manual of devices intended for controlled use shall also include information relating to the operating
characteristics of the device; the operating instructions to ensure compliance with SAR and/or RF field
strength limits; information on the installation and operation of accessories to ensure compliance with SAR
and/or RF field strength limits; and contact information where the user can obtain Canadian information on RF
exposure and compliance. Other related information may also be included.
Le mode d’emploi des appareils destinés à l’utilisation contrôlée doit aussi inclure des informations sur
les caractéristiques de fonctionnement de l’appareil; les instructions de fonctionnement pour assurer la
conformité avec SAR et / ou les limites d’intensité de champ RF; informations sur l’installation et l’exploitation
d’accessoires pour assurer le respect des SAR et / ou les limites d’intensité de champ RF; et les coordonnées
où l’utilisateur peut obtenir des informations sur l’exposition canadienne de radiofréquences et la conformité.
Autres renseignements connexes peuvent également être inclus.

Safety Information for microTALK Radios •
Your wireless handheld portable transceiver contains a low power
transmitter. When the talk button is pushed, it sends out radio frequency
(RF) signals. The device is authorized to operate at a duty factor
not to exceed 50%. In August 1996, the Federal Communications
Commissions (FCC) adopted RF exposure guidelines with safety levels
for handheld wireless devices.
Important
FCC RF Exposure Requirements: For body-worn operation, this radio has
been tested and meets the FCC RF exposure guidelines when used with
Cobra accessories supplied or designated for this product. Use of other
accessories may not ensure compliance with FCC RF exposure guidelines.
Use only the supplied antenna. Unauthorized antennas, modifications or
attachments could damage the transmitter and may violate FCC regulations.
Normal Position
Hold the transmitter approximately 2 inches from your face and
speak in a normal voice, with the antenna pointed up and away.
