(1) Such 24 VDC power supply must be used for the V690 Series only and must not be connected to any other devices nor appara-
tuses.
(2) Voltage of such DC power supply must be within the specified rating (24 VDC +10%-15%).
6. Be sure to follow any other Warnings, Cautions and Correct Usage mentioned in this manual.
.
1. Do not install model V690-HMG01, model V690-D8KR01 and model V690-L01 in the following areas:
• Place exposed to the direct sunlight.
• Humid place where moisture condensation may occur.
• Place affected by vibration or impact.
2. Preliminary check of installation site.
This device uses the frequency band 2450 MHz for the communication between an antenna and tag. Some of radio equipment, such
as wireless LAN, cellular phone, personal handyphone system and transceiver, motor and switching power supply may generate a
radio wave (noise) which affects the communication with a tag. If you must use this device near such heater, we would like to ask
you to check the influence in advance.
To minimize general influence of noise, follow the instructions below:
• Ground any metallic material located around this device according to Class D (Class III).
• Wire this device keeping away from high voltage and heavy current.
3. Ambient environment and communication range
• The communication range varies depending on the installation site environment. This is because a metal material and the ground
reflect a radio wave, and water and human body absorb it. Locate an antenna and tag in the communication range and check the
radio wave environment in advance.
• The Read/Write antenna model V690-HMG01 has a communication test command to check the radio wave environment at a
working site. (Refer to Section 3-5.)
4. Be sure to ground any ground terminal according to Class D (conventional Class III). Otherwise, performance may deteriorate.
5. Cleaning of model V690-HMG01, model V690-D8KR01 and model V690-L01
• Do not use any thinner. Resin material and case paint are dissolved by thinner.

Laws and Standards

1. Radio interference between radio stations
The frequency 2450 MHz band (2434.25 - 2465.75 MHz) used by the microwave RFID system V690 is designated for second-gen-
eration low-power data communication system (wireless LAN), local area radio station (a license required) for mobile object identi-
fication and specified low-power radio station (no license required) as well as industrial, scientific or medical equipment such as
microwave oven. Therefore, the radio interference is expected in such frequency band. Moreover, the cellular phone and personal
handyphone system (900 MHz - 1900 MHz) may generate the radio interference.
2. Possible trouble due to ratio interference
• Communication failure in RFID system
The radio wave from an ID tag to antenna is weak and, therefore, the communication between the antenna and ID tag may fail due
to radio interference caused by any other devices. Keep sufficient space between the RFID system and any other devices. For the
space, refer to Section 7-6.
• ID tag battery power loss
An electronic circuit in the ID tag is started by a radio wave of other device and the battery power may be consumed considerably.
V690 has a tag power-saving function (refer to Section 3-7) to control the battery power. Nevertheless, the battery power may be
still consumed depending on a working environment. So, keep sufficient space between the ID tag and any other devices. For the
space, refer to Section 7-6.

2-2-4 Battery Life Characteristic
The ID tag contains a battery. The charts below show the relation between the ID tag battery life, number of communication bytes and
ambient temperature. The battery life means the time until the battery voltage alarm has been given.
2-2-5 Battery Voltage Alarm Function
When the voltage of ID tag battery becomes low, "7B" is returned to the termination code when a tag communication command (Read
or Write) is executed.
Correct Usage
After the termination code 7B was generated, the ID tag can be used for approximately one month in a normal situation.
However, we recommend you to replace the tag with a new one immediately.
