1. GENERAL INFORMATION
1.1. Introduction
This manual should be carefully read prior using and/or opening any AR 6X1 Acoustic Release,
keeping in mind that IXSEA-OCEANO will not be responsible for any damage due to misuse or
misinterpretation of this manual by a non qualified operator.
1.2. IXSEA-OCEANO Products Designation
Every IXSEA-OCEANO product is identifiable by its alphanumeric designator. This consists of
a series of letters and numbers. The first two letters designate the product type.
Example:
AR = Acoustic Release
TT = Telecommand Transmitter
PS = Power Supply
RM = Rangemeter
ES = Echo Sounder
RT = Recoverable Transponder
MT = Miniature Transponder
Etc....
The typical designator will have two letters followed by three numbers. If additional designation
is required, more letters will follow the numbers.
Example: AR 661 CS
1. A = Type of Equipment
2. R = Type of Equipment
3. 6 = 6th generation
4. 6 = 6000 meters max. Depth
5. 1 = Low Frequency Band
6. C = 0.5 ton max. Load
7. S = Stainless steel
1 & 2: Type of Equipment
3: Mark of Series (electronics configuration)

1.3. Description of the Acoustic Release
1.3.1. General
The AR 6X1 series Acoustic Releases are multipurpose acoustic receivers/transmitters, which
use a secure low frequency command code structure for reliable deep-sea operations. These units
can execute acoustic remote controls such as acoustic replies and/or releases.
AR 6X1 unit is fitted with a ranging function (through the "RANGE" telecommand code) to
assist relocation.
The codes are transmitted with a telecommand unit (model TT 201 or TT301).
Acoustic commands to activate the remote control use a secure and reliable FSK-2 states
telemetry link with more than 30 000 codes.
AR 6X1 series use C-MOS technology and signal processing at very low current consumption.
1.3.2. Accessories
AR 6X1 units are supplied as standard with:
- A wooden shipping container
- A user manual
Upon request, IXSEA-OCEANO can provide with:
- Floats
- Flashes
