The recorder is made in a small, ergonomic housing with a modern graphical display and a built-in thermal printer. It is powered by a built-in battery that allows you to work without a charger for 48 hours. 

The set includes a car holder for mounting the device in the driver's cabin and a car charger.

The recorder has 4 temperature measurement channels and 4 signaling channels for door opening operation. Temperature sensors are connected to the recorder completely wirelessly. They are powered by the 1400mAh (removable) battery with  power supply from vehicle installation 12...24V DC ±10%(battery life minimum one year). Each wireless sensor has a built-in temperature probe and the ability to connect the door open sensor. For each wireless sensor, you can also connect a one additional temperature probe via a 10mb cable sensor (Cable sensor DR203).  As a result, the wireless sensor can, for example, be mounted directly in the refrigeration chamber and measure the ambient temperature and, in addition, the second temperature can be measured by a cable probe inserted into the refrigerator compartment or another fridge. After connecting the door limit sensor, each chamber door open and close operate can be signaled and recorded. Sensors are designed to work in hard environmental conditions (low temperatures, high humidity) with IP-65 protection. Cable probes with stainless steel measuring tips allow direct food contact.

DR-203 is designed to monitor and record temperature. Built-in non-volatile memory allows you to record 125,000 measurements points (memory: 3 years at the memorization frequency of 15 minutes). The interval for saving data to the memory can be set in the range from 1 min to 24 hours. When the memory is full, the recorder works in a loop, the oldest samples  are overwritten by new measurements points.

The recorder can work in one of two modes:
- continuous registration
- registration of deliveries (only during the course)
In the first mode, the device records the measurements all the time and can save data even after switching off the recorder (if the Auto-OFF parameter set = NO) or loss of communication with radio sensors. It is possible thanks to the sensor's cache memory (1000 measurements points), which saves the data to it's own memory and sends it after regaining communication with the recorder.
In the second case, the registration data process is switched on and off with the every start and stop button operate, which simultaneously marks the start and end of the course.
During operation, the recorder indicates the current temperature of the sensors, time and alarm thresholds messages. After pressing the info button, you can display the state of the sensors and the minimum and maximum temperature values ​​measured since the device was turned on.

The built-in menu allows for a wide configuration of the device:
- temperature alarm thresholds for each sensor
- sound signaling of alarms
- entering the names of sensors and user descriptions in the header
  and footer of the print report by built in printer
- choosing a language, setting the date, time and time zone
- selection of the registration method and it's parameters
- bluetooth communication settings

The parameters menu is divided into two groups:
- basic for the driver
- advanced for the service department
Access to the service department menu can be password protected. After entering the password, the memory data can be deleted and all parameters settings can be restored to the factory settings.
