+====== rEyKG LKD210 ======
+This is transportable small EKG monitor originally used in ambulance cars.
+=== Field operation manual ===
+  - Prerun check:
+    * Batteries: Displayed current should be more than 120 uA. If not, charge before use.
+    * Amplifier set to zero
+    * Open the display lid
+  - Connect EKG cable to U1
+  - Connect EKG cable to subject:
+    * RED -> right hand
+    * YELLOW -> left hand
+    * BLACK -> right leg
+    * GREEN -> left leg
+  - Power ON:
+    * 1st time it will not start
+    * 2nd time it will boot up (wait few secs)
+  - Measuring:
+    * Select circuit (svod)
+    * Wait for signal to stabilize
+      - Press amplifier down to zero the signal
+      - If running away, press again
+    * Set speed
+    * Set brightness to usable minimum
+  - Power OFF:
+    * Disconnect subject
+    * Press power off
+    * Close the lid
+<note warning> Do NOT touch contrast and vertical shift </note>
+=== Recharging ===
+<note warning>
+Recharge if displayed current is lower than 120 uA!
+Do NOT use when recharging!
+</note>
+  - Screw out batteries (back panel)
+  - Pull out charger + connectors
+  - Charger LED:
+    * Blue = fully charged
+    * Red = charging
+  - Power source - any 5V (build in microUSB connector)
+  - Recharge BOTH batteries, ONE in a time
+  - Screw charge + connectors back
+  - Runtime ~6 hours
+=== PC ===
+  - Set brightness to minimum
+  - Connect Arduino cable to C2 (SW same as [[project:medlab/ekg]])
+  - BLACK wire is ground
+  - Set signal amplifier to reasonable minimum
+Script for gnuplot to display all circuits (svody) in one plot. Let the circuits be: 1.txt for I, 2.txt for II,... 6.txt for aVF.
+When using WXT terminal, run it in persistent mode "gnuplot -p raykg.gnuplot"
